The properties of octa(4-tert-butylphenyl)tetrapyrazinoporphyrazine in 2-methylpyridine were studied. During the acid-base interaction of molecules, a kinetically stable complex was formed with proton transfer. The addition of morpholine, piperidine, n-butylamine, and diethylamine to 2-methylpyridine led to the destruction of this complex, unlike the addition of tert-butylamine and triethylamine.

Abstract:

According to our quantum and chemical calculations 4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylic acid imidazolide is theoretically almost as reactive as its 2-carbonyl analog, and it forms the corresponding N-pyridyl-4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxamides with many aminopyridines. However, in practice, the sulfo group introduces significant changes at times and prevents the acylation of sterically hindered amines. One of these products was 2-amino-6-methylpyridine. Thus, it has been concluded that aminopyridines interact with imidazolide in aromatic form where the ta

The work includes synthesis and characterization of new ligand and its complexes with divalent metal ions such as cobalt, nickel, copper and zinc. This project includes firstly, the synthesis of Schiff base by reacting P-aminoacetophenone with 2-amino-6-methylpyridine by the reflux reaction for 6 hr. and at 70 ° C. The second step involves the synthesis azo-Schiff base containing ligand which was prepared by the reaction of the Schiff base with the heterocyclic 1,2,4-triazole. The prepared ligand was characterized using spectroscopic methods such as Infrared spectrum, UV-visible spectrum, 1HNM

These compounds have a 2D sheet structure because of their strongly determinate self-assembly process. An octahedral FeII ion is coordinated with the nitrogen atoms of[AgI(CN)2 linear units at equatorial positions and monodentate pyridine derivatives at the axial position. The layers construct a parallel stacking array. Compounds 1–3 show pa
