Reductions of imine compounds 2-methoxy-N-(1-(pyridin-2-yl)ethylidene)ethanamine (L1), 2-methoxy-N-((pyridin-2-yl)methylene)ethanamine (L2), N,N-diethyl-N-((pyridin-2-yl)methylene)ethane-1,2-diamine (L3) and 2-((pyridin-2-yl)methyleneamino)ethanol (L4) using NABH4 produced their corresponding amine analogues N-(2-methoxyethyl)-1-(pyridin-2-yl)ethanamine (L1a), 2-methoxy-N-((pyridin-2-yl)methyl)...

A family of ditopic hexadentate ligands based on the parent compound 2,6-bis(6-(pyrazol-1-yl)pyridin-2-yl)-1,5-dihydrobenzo[1,2-d:4,5-d’]diimidazole (L) was developed and synthesized by using a straightforward condensation reaction, which forms interlinking central benzo[1,2-d:4,5-d’]diimidazole bridge in ligand backbone. The two secondary amine groups benzodiimidazole unit tautomerize allow fo...

In this communication, we present the crystal structure of a secondary amine: 4-chloro-N-(1-(pyridin-2-yl)ethyl)aniline (Lb) obtained from stepwise reduction an imine, (E)-N-(4-chlorophenyl)-1-(pyridin-2-yl)ethan-1-imine (La) with sodium borohydride. The was characterized by FT-IR, 1H and 13C NMR, Mass Spectroscopy X-ray diffraction.

The crystal structures of di-μ-chlorobis[2-(5-methyl-pyridin-2-yl-κN)phenyl-κC(1)] diplatinum(II) (1) and chloro(N,N-dimethylformamide-κO)[2-(5-methyl-pyridin-2-yl-κN)phenyl-κC(1)]platinum(II) (2) have been determined by means the X-ray diffraction. Both complexes cocrystallize in monoclinic space group C2/c with a = 39.5457(18) Å, b 7.2482(4) c 21.2269(10) Å β 121.460(2)°. asymmetric unit cons...

The study investigated the corrosion-inhibitory properties of three synthetic triazole Mannich bases on C1018 carbon steel using various electrochemical techniques. inhibitors, namely 4-amino-2-[(4-methylpiperazin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (4MPT), 4-amino-2-[(piperidin-1-yl)methyl]-5-(pyridin-4-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (PPT) and 4-ami...

Prevalence to the various biological activities of imidazo[4,5-b] pyridine nucleus has promoted us for an attempt of one pot synthesis of (1H, 3H) imidazo [4,5-b] pyridines (desazopurines) as inhibitors of Lumazine synthase in M. tuberculosis (PDB 2C92). Major advantage of Lumazine synthase enzyme behind consideration as target protein in docking study is its absence in mammalian cell but prese...

The title compound, C13H10N2O2 [also called 1-(pyridin-2-yl)-3-(pyridin-3-yl)propane-1,3-dione], features an almost planar (r.m.s. deviation = 0.0095 Å) central C3O2 core consolidated by an intra-molecular hy-droxy-O-H⋯O(carbon-yl) hydrogen bond. Twists are evident in the mol-ecule, as seen in the dihedral angles between the central core and the 2- and pyridin-3-yl rings of 8.91 (7) and 15.88 (...

The aim of the work. 1,2,4-triazole derivatives possess a wide range pharmacological activity, so they are used for development drugs and active pharmaceutical ingredients. Due to reactivity 1,2,4-triazoles there many options their further structural modification on different reaction centers. Therefore, work was obtain new S-substituted 1,2,4-triazole-3-thiols, study physicochemical parameters...
