Involvement of putrescine in osmotic stress-induced ABA signaling in leaves of wheat seedlings

To elucidate one mechanism by which putrescine (Put) functions in plant signaling under osmotic stress, Put and ABA contents, and plasma membrane-NADPH oxidase (PM-NOX) activity were detected in wheat seedling leaves. Under osmotic stress, ABA and Put contents, PM-NOX activity, and PM-NOX-dependent O2.- production all increased. The inhibitor tungstate (T) of ABA bio-synthesis reduced the increases in ABA and Put contents under osmotic stress. The inhibitor D-arginine (D-Arg) of Put bio-synthesis didn’t reduce osmotic-induced increase of ABA, but it inhibited the increases of PM-NOX activity and O2. – production, and the inhibitory effects were reversed by exogenous Put. These findings suggested that ABA might regulate Put biosynthesis, and Put might regulate PM-NOX activity. Treatments with three inhibitors imidazole (I), diphenylene iodonium (DPI) and pyridine (P) of PM-NOX reduced significantly not only O2. – production, but also the stress-induced increase of Put content, which indicated that O2. – production might regulate Put biosynthesis. Treatments with EGTA (Ca2+ chelator), La3+ and verapamil (V) (Ca2+ channel blockers) reduced significantly the stress-induced increase of Put content, which suggested that Ca2+ might regulate Put biosynthesis. With these findings, it could be concluded that Put was involved in ABA signaling induced by osmotic stress via regulating PM-NOX activity in wheat seedling leaves.

Synthesis, structure and catalytic activity of rare-earth metal amino complexes incorporating imino-functionalized indolyl ligand

The reactions of the imino-functionalized indolyl ligand (HL, L = 3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5N) with the rare-earth metal amides [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) producing different types of rare-earth metal amido complexes were investigated. The reactions of HL with 1 equiv. of [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) generated a series of hetero-nuclear bimetallic rare-earth metal amino complexes {[eta(1):mu-eta(2)-3-(4-Me2N-C6H4CH=N-CH2CH2)C-8 H-5]RE[N(SiMe3)(2)](2)(mu-Cl)Li(THF)} (RE = Y(1 ), Sm(2), Gd(3), Er(4), Yb(5)). By extending the reaction time, only the reaction of HL with [(Me3Si)(2)N](3)Gd(mu-Cl)Li(THF)(3) gave an unexpected binuclear rare-earth metal complex {[(mu-eta(5) :eta(1)):eta(1):eta(1)-3-[(Me2N)(2)-C14H9]-(NCH2CH2-C8H5N)(2)]Gd-2[N(SiMe3)(2)](3)} (6 ) incorporating a novel polycyclic ligand through C-C and C-N coupling. Treatment of HL with [(Me3Si)(2)N](3)Sm(mu-Cl)Li(THF)(3) in a 2:1 ratio generated the bis(indolyl) heteronuclear bimetallic rare-earth metal amino complex {(eta(1):eta(1)-[mu eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5]Li[mu-eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5])Sm[N(SiMe3)(2)](2)} (7) in low yield probably due to accompanying with the formation of the complex 2 . The above results indicated that reaction conditions play important roles in the formation of different coordination modes of the imino-functionalized indolyl rareearth metal amido complexes. All new complexes 1-7 are fully characterized including X-ray structural determination. The catalytic activity of complexes 1 7 for the addition of amines to carbodiimides was explored. The results showed that all complexes displayed an excellent activity towards the addition of amines to carbodiimides producing guanidine under solvent-free condition. (C) 2020 Elsevier B.V.

Hybrid material by anchoring a ruthenium(ii) imine complex to SiO2: preparation, characterization and DFT studies

Ruthenium-silica hybrid material (RuCl2(PR3)(2)-2-PyCH-AMPTSi/SiO2) was prepared and characterized by various spectroscopic techniques. A deconvolution procedure was applied to the spectroscopic data to deconstruct the overlapped bands. A density functional theoretical approach was applied to get insights into the electronic structure of the ruthenium coordination site and the functional RI-PBE-D3/Def2TZVP basis set was used for the optimization. Relativistic effects were considered using the zero-order regular approximation (ZORA). The anchoring process, evinced for each step of the synthesis of the hybrid material, was tracked by FT-IR analyses. The transitions observed in the FT-IR spectra were verified by DFT analyses, which agree with the experimental data. In the DRS-UV-Vis spectra, three main bands were detected by the deconvolution procedure that correspond to the charge transfer transitions, with the main contributions from ruthenium-chlorine and imine-pyridine fragments. TD-DFT results reveal that ruthenium-chlorine antibonding orbitals act as main charge donors, while pyridine-imine is the main charge acceptor.

New Schiff bases derived from benzimidazole as efficient mercury-complexing agents in aqueous medium

In this paper, we describe a very fast and efficient synthesis of series of new Schiff bases L1-L5 derived from benzimidazole. It was found that, these compounds react efficiently with mercury ions to afford the corresponding complexes COP1-COP5 in nearly quantitative yield. This reaction takes place in water and in most of the usual solvents. The study of the complexation reaction of L1 with other metal ions has been carried out and shown that L1 can efficiently coordinate with Cu2+ and Co2+. In addition, the reactivity of the benzimidazole Schiff bases has been compared with some reported pyridine analogues and checked with DFT calculations. It has been found that both experimental results and theoretical calculations confirm that the benzimidazole Schiff bases are clearly more reactive than their pyridine analogues.

Optical detection of cyanide by palladium(II)-dithiazolopyridine probe at the parts per billion level

The ensemble of 2,6-bis(2-chlorophenyl)dithiazolo[4,5-b:5′,4′-e]pyridine 1 with Pd2+ ions (1 center dot Pd2+) was prepared for the detection of cyanide ions (CN over bar ) in 50% aqueous methanol. Among the tested metal ions, only Pd2+ sensitively induced the red shift of the absorption bands and the complete decrease of fluorescence emission. The detection limit toward Pd2+ was 2 ppb. The ensemble 1 center dot Pd2+ selectively and rapidly detected a low concentration of cyanide ions by a colorimetric change (40 ppb) as well as a turn-on fluorescent response (5 ppb). Job’s plot revealed the complex formation with 1:1 stoichiometry. The binding and replacement mode of 1 center dot Pd2+ and CN over bar were also confirmed by H-1 NMR titrations and IR analysis. In general, a fast and selective recognition of CN over bar is reported.

Novel silver(I) cluster-based coordination polymers as efficient luminescent thermometers

By employing a triazole-pyridine-containing ligand, two novel coordination polymers with Ag(I) clusters exhibiting different architectures have been successfully constructed. Structural analysis indicates that diverse coordination modes of the N-donor linker are responsible for the network difference for these two compounds, affording an isolated cluster for 1 and a 2D framework for 2, respectively. Compound 1 features a butterfly-shaped [Ag-8(bptp)(4)(H2O)(2)] cluster wherein strong argentophilic interactions could be observed. The linkage of Ag(I) with N and I centers gives rise to a tetranuclear building unit [Ag-4(bptp)(3)I] in 2, which is further extended to a 2D network with the assistance of the N-donor linkers. The syntheses and crystal structures have been investigated. Solid-state photoluminescence emissions as well as luminescence lifetimes of 1 and 2 have also been studied. Moreover, temperature-dependent luminescence tests show that an excellent linear relationship between temperature and emission intensity in the ranges of 77-298 K and 77-200 K could be observed for compounds 1 and 2, respectively. The wide temperature sensing range especially for 1 implies that they could act as promising ratiometric fluorescence molecular thermometers.

Blend membranes based on N1-alkyl-substituted imidazolium functionalized polymers and aromatic polyethers: influence of N1-alkyl substituent on properties and alkaline stability

N1-alkyl (octyl and dodecyl)-substituted imidazolium-based PVBC homopolymers have been synthesized via N-quaternization reaction of N1-alkyl imidazole and PVBC precursor homopolymer bearing reactive benzyl chloride moieties. Due to their poor film forming properties and water solubility, these homopolymers were blended with aromatic polyethers bearing main chain pyridine units at different compositions in order to study the effect of alkyl chain length on morphology, water uptake, swelling ability and chemical stability of the prepared membranes. The B2 blend membrane with the highest N1-dodecyl-substituted imidazolium PVBC content (65 wt%) exhibited the highest water uptake (54%) despite its lower IEC value compared to the corresponding one containing N1-octyl-substituted imidazolium PVBC, low swelling ratio and a phase separated morphology. Evaluation of the chemical stability in 3.6 M KOH solution at 80 degrees C for 7 days revealed the degradation of imidazolium via ring opening, as evidenced by ATR-FT-IR spectroscopy. Therefore, new blends having as second constituent, the N1-alkyl-substituted imidazolium functionalized poly(PVBC-co-AA(20)) copolymers containing acrylic acid units were fabricated targeting to the improvement of chemical stability via ionic cross linking. The prepared D1 and D2 blend membranes containing 60 and 65 wt% dodecyl-imidazolium functionalized poly(PVBC-co-AA(20)) copolymer content, respectively, were flexible, exhibited moderate IECs (1.47-1.60 meq/g) and sufficient water uptakes (up to 30%). D2 blend membrane showed excellent chemical stability after testing in 3.6 M KOH solution at 80 degrees C for 30 days, as confirmed by ATR-FT-IR spectroscopy and TGA analysis. The excellent chemical stability can probably be attributed to the steric hindrance effect of N1 dodecyl substituent which effectively protects the C2 position of imidazolium from hydroxide attack as well as to the formation of a dense, ionic cross-linked structure that hinders hydroxide penetration.

Study on the effect of substituents on the structure, volatility, and fluorescence of N-(Alkyl or TMS)-2-pyridinamine diethyl aluminum complexes

A series of N-(Alkyl or TMS)-2-pyridinamine ethyl aluminum complex with different substituents were prepared and characterized. When the substituent is n-propyl and n-butyl, the N-(Alkyl or TMS)-2-pyridinamine diethyl aluminum complexes agglomerate at -30 degrees C. On the contrary, when the substituent is isopropyl and trimethylsilyl, the agglomerate is not easily observed. Compared with the N-(Alkyl or TMS)-2-pyridinamine diethyl aluminum complexes of isopropyl, trimethylsilyl, and isopropyl, the H-1 NMR spectra of the pyridine part of N-(n-propyl)-2-pyridinaminoe diethyl aluminum have three sets of peaks. The extra peak may come from the dimer and trimer. Due to the high tension of the quaternary ring and pyridine’s influence on the bonding, pyridine did not participate in the coordination, and the optimized monomer structure determines that the monomer is not a quaternary ring structure. Considering the rapid condensation of the liquid product of N-(n-propyl)-2-pyridinaminoe diethyl aluminum at -30 degrees C, the existence form of compound 2 at different temperatures was determined by variable temperature NMR and simulated NMR. When the temperature reaches 60 degrees C, the structure of N-(n-propy1)-2-pyridinaminoe diethyl aluminum is a monomer (a stable structure formed with toluene). At -30 degrees C, the monomer dissociates from the stable structure formed with toluene, and the dimer increases with it. The thermodynamic properties of ethyl aluminum complexes with different substituents were studied by thermal analysis. It was found that the ethyl aluminum complexes with two substituents, isopropyl and trimethylsilyl and difficult to dimerize, were more volatile. The maximum fluorescence wavelength of the complex is affected by the substituents. The spatial and electronic absorption effects of trimethylsilyl make the fluorescence spectrum of the complex 6 blue shift to 406nm. On the contrary, due to the small steric hindrance of n-Propyl, and the easy bonding between Al-N, the fluorescence spectrum of complex 2 shifts to 464nm. (C) 2020 Elsevier B.V. All rights reserved.

Nickel(II) Complexes with Electron-Rich, Sterically Hindered PNP Pincer Ligands Enable Uncommon Modes of Ligand Dearomatization

We report the reactivity and characterization of hydride, methyl, and bromo Ni-II complexes with a new class of electron-rich and sterically hindered PNP pincer ligands, Me4PNPR (R = Pr-i, Bu-t), in which a classical metal-ligand cooperative mode of reactivity via CH2 arm deprotonation is blocked by methylation. This enables new, uncommon modes of PNP ligand dearomatization that involve reactivity in the para position of the pyridine ring. In particular, the reduction of [(Me4PNPiPr) (NiMe)-Me-II]B(Ar-F)(4) with KC8 leads to the formation of a new C-C bond via dimerization of two complexes through the para position. This reactivity stands in sharp contrast to the previously reported bromo or chloro complexes, where stable Ni-I halogen moieties are formed. Computational analysis showed a greater propensity for ligand-centered radical formation for the presumed intermediate one-electron-reduced species. UV-induced homolysis of the Ni-II-Me bond in [(Me4PNPiPr) (NiMe)-Me-II]B(Ar-F)(4) leads to the formation of a Me radical detected by radical traps and Ni(I )intermediates that can be trapped in the presence of halide ions to give previously characterized, stable Ni-I halogen complexes. In addition, treatment of the bromo complexes [(Me4PNPR)(NiBr)-Br-II]BPh4 with a powerful hydride source, LiBEt3H, leads to the reduction of the pyridine ring and the formation of Ni-II complexes with an anionic amide donor reduced pincer ligand, although aromatic Ni-II hydride complexes could also be obtained with a weaker hydride source. We have observed that steric bulk at the phosphine donors controls the reactivity of the resulting Ni(II)H( )complexes. While t-Bu-substituted [(Me4PNPtBu) (NiH)-H-II]Y(Y=BPh4, B(Ar-F)(4)) does not react with O-2, the less sterically hindered Pr-i-substituted [(Me4PNPiPr)(NiH)-H-II]Y reacts instantaneously to give an unstable superoxide adduct that can be observed by EPR.

Steric and electronic modulation of iron catalysts as a route to remarkably high molecular weight linear polyethylenes

Five structurally related bis(arylimino)pyridine-iron(ii) chloride complexes, [2-[CMeN{2,6-{(4-FC6H4)(2)CH}(2)-4-NO2}]-6-(CMeNAr)C5H3N]FeCl2 (Ar = 2,6-Me2C6H3 Fe1, 2,6-Et2C6H3 Fe2, 2,6-i-Pr2C6H3 Fe3, 2,4,6-Me3C6H2 Fe4, and 2,6-Et-2-4-MeC6H2 Fe5), incorporating one N-2,6-bis{di(4-fluorophenyl)methyl}-4-nitrophenyl group and one distinct N-aryl group, have been prepared in good yield through the interaction of the corresponding free ligands (L1-L5) with FeCl2 center dot 4H(2)O. All ferrous complexes were paramagnetic which was manifested by broad and highly shifted peaks in their H-1 NMR spectra. The marked steric imbalance imposed by the two inequivalent N-aryl groups was a key feature highlighted in the molecular structures of representative complexes Fe1 and Fe2. Upon activation with either MAO or MMAO, Fe1-Fe5 all exhibited high activities for ethylene polymerization with good thermal stability [activities as high as 1.58 x 10(7) g (PE) mol(-1) (Fe) h(-1) at 60 degrees C], affording especially high molecular weight linear polyethylenes (3.92 x 10(5) g mol(-1) at 70 degrees C; T-m > 130 degrees C). To the best of our knowledge, the molecular weights of the polyethylenes produced by the current class of iron catalysts exceed the highest values reported for related bis(imino)pyridine-iron catalysts to date; changes in the ortho-R-1 substitution pattern offered some additional fine control of the molecular weight. Moreover, the nature of the aluminoxane co-catalyst employed had a noticeable effect on the polymer end group composition. When using MAO, unsaturated polymers containing both vinyl and n-propyl end groups were evident, whereas with MMAO, fully saturated polymers were generated containing both isobutyl and n-propyl end groups.

Synthetic Route of 94-44-0, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 94-44-0 is helpful to your research.
