Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Batori, S; Csanyi, D; Takacs, D; Egyed, O; Riedl, Z; Hajos, G. The CAS is 91-02-1. Through research, I have a further understanding and discovery of Phenyl(pyridin-2-yl)methanone

N-aminopyridyl ketone salts were reacted with formamide to yield heteroaromatic pyrido[2,1-f][1,2,4] triazinium salts. Upon storage of these products in the presence of water, formation of covalent hydrates have been observed. Reaction of the same starting compound with urethane yielded 3-chloropyrido[2,1-f][1,2,4]triazinium salt which readily reacted with secondary amines to afford 3-amino derivatives. An analogous ring closure reaction of 2-formylaminomethyl- and formaminobenzylpyridine allowed the synthesis of the partially reduced 3,4-dihydropyrido[2,1-f][1,2,4]triazinium compounds. The cyclization procedure was also applied for the synthesis of the related pyrimido[2,1-f][1,2,4]triazinium salt. (C) 2018 Elsevier Ltd. All rights reserved.

behavior of cucurbituril-bipyridinium pseudorotaxane ligand by utilizing meta-functionalized bipyridinium dicarboxylate guest. A tailored pseudorotaxane precursor involving 1,1′-(hexane-1,6-diyl)bis(3-cyanopyridin-1-ium) bromide (C6BPCN3) and cucurbit[6]uril (CB[6]) has designed and synthesized. Through in situ hydrolysis of the pseudorotaxane ligands and their coordination assembly with uranyl cations, seven new uranyl-rotaxane coordination polymers URCP1-URCP7 have been obtained under hydrothermal conditions in the presence of different anions. It is demonstrated that the variation of carboxylate groups from para- to meta-position greatly affected the coordination behaviors of the metafunctionalized pseudorotaxane linkers, which are enriched from simple guest-only binding to host-guest simultaneous coordination and synergistic chelating. This effective regulation on uranyl coordination of supramolecular pseudorotaxane can be attributed to the proximity effect, which refers to the meta-position carboxyl group being spatially closer to the portal carbonyl group of CB[6]. Moreover, by combining other regulation methods such as introducing competing counterions and modulating solution acidity, the nuclearity of the uranyl center and the coordination patterns of the pseudorotaxane ligand can be diversely tuned, which subsequently exert great influence on the final dimensionality of resultant uranyl compounds. This work presents a large diversity of uranyl-based coordination polyrotaxane compounds with fascinating mechanically interlocked components and, most importantly, provides a feasible approach to adjust and control the metal coordination behavior of the pseudorotaxane ligand that might expand the scope of application of such supramolecular ligands.

Novel 3-Amino-1-hetarylfluorene derivatives have medicinal uses and challenging transformation in organic synthesis have been synthesized via decyanation process. Surprisingly, the alkylated compounds derived from 3-Amino-1-hetarylfluorenes were obtained via further nucleophilic substitution to the 9-C and 3-N positions of the fluorene ring because of the harsh reaction condition employed. The synthesized compounds were characterized by spectroscopic techniques as well as X-ray single crystal diffraction analysis. This new family of blue emitting fluorene derivatives have low to moderate quantum yields (the largest value of Phi(F) = 0.52 for compound 15). (C) 2019 Elsevier Ltd. All rights reserved.

Herein we report, a mononuclear, highly fluorescent zinc(ii) complex Zn(L)(N-3)(H2O) (1) that was prepared by an easy one pot method, in which the tridentate Schiff base ligand (E)-4-((2-(dimethylamino)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (HL) was generated in situ. The compound is characterized by various spectroscopic techniques, and its structure was determined by single crystal X-ray diffraction studies. DFT calculations were used to understand the electronic structures of the ligand and the complex, and TD-DFT calculations were performed to interpret the nature of the electronic transitions observed in their UV-vis spectra. In the complex, Zn(II) is found to be penta-coordinated with one azide ligand, an aqua ligand and a monoanionic tridentate N,N,O-donor ligand. In an aqueous methanol (1:9 by volume) solution, at the physiological pH (0.01 M Tris-HCl buffer, pH 7.4), compound 1 exhibits an intense greenish blue fluorescence (lambda(ex) 390 nm, lambda(em) 462 nm), whose intensity is about 17-fold stronger than that of the free ligand. Compound 1 is found to show significant DNA binding activity. The pyridoxal appended tridentate ligand can be used for the bio-imaging of Zn(II).

A chemical sensor composed of pyridoxal hydrochloride schiff base based on diarylethene (1O) was synthesized. Its photochemical properties and selectivity to ions were further studied. The chemosensor could detect cyanide effectively and is almost undisturbed by other ions. When titrating CN-, the reaction aroused a distinct change in the absorption spectrum with the color change from transparent to yellow, and the fluorescence intensity centered at 562 nm was increased 68 folds. It also exhibited a good fluorescence sensing of Mg(2+ )with high selectivity and sensitivity. Upon addition of Mg2+, its emission intensity enhanced 110 folds, with the color change from dark to bright blue. Its good spectral response could be applied to molecular logic circuit. Moreover, the chemosensor could be made into test paper strips for the qualitative and quantitative detection of CN- and Mg2+.

The synthesis and solid state structural, spectral and electrochemical solution characterization of [Cu(L)(acpy)]ClO4 1 and [Cu(L)(NO3)]( )2 [where L = N'[(E)-phenyl(pyridin-2-yl)methylideneithiophene-2-carbohydrazide and acpy = 2,6-Diacetylpyridine] have been done by elemental analysis, UV-vis, FTIR, electrochemical techniques (CV and DPV) and electron paramagnetic resonance (epr) spectroscopy. The single crystal structures were solved by the X-ray diffraction technique. In complex 1, copper ion is in a distorted octahedral environment. The geometry of copper(II) in complex 2 is distorted square pyramidal (tau = 0.201). The mono deprotonated, HL ligand act as a tridentate to a copper(II) ion. On the basis of density functional theory (DFT) calculation, the electronic excitations involve transitions mainly from metal ligand bonding mostly the alpha-LUMO within the dominant Cu d(xy) character and to alpha-LUMO+1. Epr spectra for polycrystalline samples showed the copper(II) hyperfine features as well as half-field signal which are appropriate for Delta M-s = +/- 2 of dimers. Presence of half-field signal in 1 is due to solid-solid interaction (intra-molecular) where as in 2 the nature of interaction is intra-molecular. The antioxidant superoxide measurements show that the both complexes 1 and 2 behave as superoxide mimic in alkaline nitro blue tetrazolium chloride assay. (C) 2020 Elsevier B.V. All rights reserved.

Microwave-assisted approach was utilized as green approach to access a series of 2-pro pylquinoline-4-carbohydrazide hydrazone derivatives 10a-j of aromatic and heteroaromatic aldehydes in highly encouraging yields. It involved four steps reaction which was initiated with ring opening reaction of isatin in a basified environment and subsequent cross-coupling with pentan-2-one to produce compound 7. Esterification of 7 in acid medium led to the formation of compound 8 which was reacted with hydrazine hydrate to access 9 which upon microwave-assisted condensed with aromatic and heteroaromatic aldehydes furnished the targeted compounds 10a-j. The structures of 10aj were confirmed by physico-chemical, elemental analyses and spectroscopic characterization which include UV, FT-IR, H-1 and C-13 NMR as well as DEPT-135. The targeted compounds 10a-j, alongside with gentamicin clinical standard, were investigated for their antibacterial efficacies using agar diffusion method. 2-Propyl-N’-(pyridine-3-ylmethylene) quinoline-4-carbohydrazide 10j emerged as the best antibacterial hydrazide-hydrazone with lowest MIC value of 0.39 +/- 0.02 – 1.56 +/- 0.02 mu g/ mL across all the organisms screened.
