A half-salamo-based pyridine-containing ligand and its novel Ni-II complexes including different auxiliary ligands: syntheses, structures, fluorescence properties, DFT calculations and Hirshfeld surface analysis

Three novel multinuclear Ni-II complexes, namely, bis{mu-2-methoxy-6-[8-(pyridin-2-yl)-3,6-dioxa-2,7-diazaocta-1,7-dien-1-yl]phenolato}bis[thiocyanatonickel(II)], [Ni-2(L)(2)(NCS)(2)], 1, bis{mu-2-methoxy-6-[8-(pyridin-2-yl)-3,6-dioxa-2,7-diazaocta-1,7-dien-1-yl]phenolato}bis[azidonickel(II)], [Ni-2(L)(2)(N-3)(2)], 2, and catena-poly[[{2-methoxy-6-[8-(pyridin-2-yl)-3,6-dioxa-2,7-diazaocta-1,7-dien-1-yl]phenolato}nickel(II)]-mu-dicyanamidato], [Ni(L)(dca)](n), 3 {dca is dicyanamide, C2N3, and HL is 2-methoxy-6-[8-(pyridin-2-yl)-3,6-dioxa-2,7-diazaocta-1,7-dien-1-yl]phenol, C16H17N3O4}, with a half-salamo-based pyridine-containing HL ligand have been synthesized and characterized by FT-IR, UV-Vis absorption spectroscopy, X-ray crystallography, Hirshfeld surface analysis and density functional theory (DFT) calculations. The central Ni-II ions in complexes 1-3 are hosted in the half-salamo-based N3O-donor cavity of the organic ligand. Complex 1 is a centrosymmetric dimer and two [Ni(L)(NCS)] units form a centrosymmetric dimeric structure, which is bridged by two phenolate O atoms. The two N atoms at the axial ends are provided by two NCS- ligands. In complex 1, each Ni-II ion has a six-coordinated octahedral geometry. Complex 2 is similar to 1, but they differ in that the auxiliary NCS- ligand is replaced by N-3(-). However, complex 3 is a one-dimensional coordination polymer constructed from [Ni(L)(dca)] units, which are connected by the auxiliary bidentate dca ligand via N-donor atoms. As with complexes 1 and 2, the Ni-II ion in 3 has a six-coordinated octahedral geometry.

Concise design and synthesis of pyridine-fused heterocycles via 6 pi- Azaelectrocyclization process of iminoalkyne derivatives

A concise and regioselective approach to the synthesis of pyridine-fused heterocycles and benzoxazepine derivatives was developed. Propargyl imines derived from aromatic aldehydes and propargyl amine underwent 6 pi-electrocyclization reactions at high temperatures in high yields to form pyridine-fused heterocycles. Application of the same methodology to aromatic imines having a hydroxyl group in the ortho position resulted in the formation of (benz)oxazepine derivatives. The formation mechanism of the products was discussed. (C) 2019 Elsevier Ltd. All rights reserved.

Synthesis and characterization of Schiff base, Co(II) and Cu(II) metal complexes and poly(phenoxy-imine)s containing pyridine unit

In the first stage, two different Schiff base ligands were prepared by the condensation of 2-amino-5-bromopyridine and 2-amino-5-chloropyridine with salicylaldehyde in methanol at the molar ratio of 1:1. Ligands: C12H9ON2Br (L1), C12H9ON2Cl (L2). In the second stage, four different metal complexes were obtained from Schiff bases with Co(OAc)(2)4H(2)O and Cu(OAc)(2)2H(2)O Molecular formulas of the metal complexes obtained were [Co-2(L1)(2)(H2O)(OCH3)]H2O, [Cu-2(L1)(2)(H2O)(OCH3)]H2O, [Co-2(L2)(2)(H2O)(OCH3)]H2O and [Cu-2(L2)(2)(H2O) (OCH3)] H2O. In the third stage, ortho-vanillin (VAN) was polymerized via oxidative polycondensation in aqueous alkaline medium with air as oxidant. Then, poly(phenoxy-imine)s were synthesized from condensation reactions of poly (ortho-vanillin) (PVAN) with 2-amino-5-bromopyridine and 2-amino-5-chloropyridine in THF medium at 60 degrees C. All synthesized compounds were characterized by spectral and electrochemical techniques. Thermal properties of the compounds were determined by TGA-DTA and DSC analyses. The molecular weights of the polymers were calculated from SEC analyses. Poly[2-((5-bromopyridin-2-yl-imino)methyl)-6-methoxyphenol] (PVANBr) and poly[2-((5-chloropyridin-2-yl-imino)methyl)-6-methoxyphenol] (PVANCl) were determined to have electrical conductivity of 10-3 S cm(-1). Electrochemical band gaps (Eg’) of PVANBr and PVANCl were calculated as 2.10 and 1.95 eV, respectively. Initial decomposition temperatures of [Co-2(L1)(2)(H2O)(OCH3)]H2O, [Cu-2(L1)(2)(H2O)(OCH3)]H2O, [Co-2(L2)(2)(H2O)(OCH3)]H2O and [Cu-2(L2)(2)(H2O) (OCH3)]H2O were found to be 309, 271, 305 and 259 degrees C, respectively.

Cooperative catalytic effects between Bronsted and Lewis acid sites and kinetics for production of methyl methacrylate on SO42-/TiO2-SiO2

Either the ethylene or isobutene-based route for industrial production of methyl methacrylate (MMA) contains the esterification step between methacrylic acid (MAA) and methanol, therefore it is necessary to develop highly active and stable catalyst. Herein, series of superacid catalysts of SO42-/TiO2-SiO2 were prepared for esterification of MAA with methanol to produce MMA. The Bronsted and Lewis acid site den-sities and their ratios in SO42-/TiO2-SiO2 could be modulated by controlling the impregnated (NH4)(2)SO4 concentration, which were identified by pyridine titration and FT-IR. And no changes in structural skeleton and crystal phase of the SO42-/TiO2-SiO2 during the acid properties regulation process were noticed with FT-IR and XRD. The cooperative catalytic effects between Bronsted and Lewis acid sites were observed through catalytic evaluation. The kinetic studies indicated the catalytic pathway followed L H mechanism and the activation barrier of forward esterification (48 kJ/mol) was greater than that of reverse hydrolysis (40 kJ/mol) step.

Development of a novel class of peroxisome proliferator-activated receptor (PPAR) gamma ligands as an anticancer agent with a unique binding mode based on a non-thiazolidinedione scaffold

We previously identified dibenzooxepine derivative 1 as a potent PPAR. ligand with a unique binding mode owing to its non-thiazolidinedione scaffold. However, while 1 showed remarkably potent MKN-45 gastric cancer cell aggregation activity, an indicator of cancer differentiation-inducing activity induced by PPAR. activation, we recognized that 1 was metabolically unstable. In the present study, we identified a metabolically soft spot, and successfully discovered 3-fluoro dibenzooxepine derivative 9 with better metabolic stability. Further optimization provided imidazo[1,2-alpha]pyridine derivative 17, which showed potent MKN-45 gastric cancer cell aggregation activity and excellent PK profiles compared with 9. Compound 17 exerted a growth inhibitory effect on AsPC-1/AG1 pancreatic tumor in mice. Furthermore, the decrease in the hematocrit (an indicator of localized edema, a serious adverse effect of PPAR gamma ligands) was tolerable even with oral administration at 200 mg/kg in healthy mice.

Rationalising Supramolecular Hydrogelation of Bis-Urea-Based Gelators through a Multiscale Approach

The current approach to designing low-molecular-weight gelators relies on a laborious trial-and-error process, mainly because of the lack of an accurate description of the noncovalent interactions crucial for supramolecular gelation. In this work, we report a multiscale bottom-up approach composed of several computational techniques to unravel the key interactions in a library of synthesized bis-urea-based gelators and rationalize their experimentally observed hydrogelation performance. In addition to density functional theory calculations and molecular dynamics, the noncovalent interaction index is applied as a tool to visualise and identify the different types of noncovalent interactions. Interestingly, as well as hydrogen bonds between urea moieties, hydrogen bonds between a urea moiety and a pyridine ring were shown to play a detrimental role in the early aggregation phase. These findings enabled us to explain the hydrogelation performance observed in a library of twelve bis-urea derivatives, which were synthesized with 58-95 % yields. From this library, three compounds were discovered to effectively gel water, with the most efficient hydrogelator only requiring a concentration of 0.2 w/v%.

Solvometallurgical process for the recovery of rare-earth elements from Nd-Fe-B magnets

The protic ionic liquid pyridine hydrochloride is known to be a non-aqueous solvent for metal oxides, including rare-earth oxides. However, its application in extractive metallurgy and especially in solvent extraction has been so far limited by its miscibility with the aqueous phase. In this paper, molten pyridine hydrochloride (165 degrees C) was used to dissolve production scrap of Nd-Fe-B permanent magnets to recover the valuable metals neodymium and dysprosium. The Nd-Fe-B scrap powder completely dissolved in just 10 min with a lixiviant-to-solid ratio of 10 g g(-1). Afterwards, non-aqueous solvent extraction was performed at high temperature (165 degrees C) by using molecular extractants (PC-88A) or ionic liquids (Cyphos IL 101). The high temperature lowers the viscosity of the solvents, so that they can be used in undiluted form. Moreover, the high temperature affects the equilibrium constants and, hence, the distribution of the metals between the two phases. In the first stage, 30 vol% PC-88A in p-cymene was used to extract dysprosium(III), whereas in the second stage 100 vol% PC-88A was used to extract most of the neodymium(III). Finally, a mixture of Cyphos IL 101-p-cymene 70:30 (wt.:wt.) was shown to efficiently extract iron(II,III) from the concentrate leachate. A conceptual flowsheet was designed, which included the recycling of the pyridine hydrochloride to lower the costs and the environmental impact of the process.
