Abstract:

Abstract Trichlorosilane, HSiCl3, forms with 3,4-dimethylpyridine in aprotic solvents a crystalline l:2-compound which is stable at room temperature and readily soluble in CHCl3. Colourless crystals of the dicationic complex, [H2Si(3,4-dimethylpyridine)4]2+ 2Cl- · 6 CHCl3 (verified by X-ray structure analysis) are obtained by dismutation of HSiCl3(3,4-dimethylpyridine)2 in CHCl3 within one week at room temperature.29Si NM R indicates that SiCl4 is generated as a second product. H2SiCl2 with 2,4-dimethylpyridine as well as MeHSiBr2 with 3,5-dimethylpyridine in aprotic solvents form 1:2-compound

Abstract:

The reaction of 4,6-dimethyl-2-thioxo-1,2-dihydropyridin-3-carbonitriles with K3[Fe(CN)6] in an alkaline medium led to the formation of a mixture of oxidation products: bis(3-cyanopyridin-2-yl)disulfides and potassium 3-cyano-4,6-dimethylpyridine-2-sulfonates. Structure of the compounds was confirmed by NMR, IR spectroscopy and high-resolution mass spectrometry data. According to the results of molecular docking, 2,2′-dithiobis(5-butyl-4,6-dimethylnicotinonitrile) exhibits affinity for the zinc finger binding site of the HIV-1 p7 nucleocapsid protein.

The structure parameters around the Cu(I) ion in pyridine (PY), 4-methylpyridine (4MPY), 2-methylpyridine (2MPY), 2,6-dimethylpyridine (26DMPY), and acetonitrile (AN) were determined by the extended X-ray absorption fine structure (EXAFS) method. The solvation structures of the Cu(I) ion in PY, 4MPY, and AN are 4-coordinate tetrahedral with Cu-N bond lengths of 205, 205, and 200 pm, respectively. In the case of 2MPY and 26DMPY, the Cu(I) ion has a 3-coordinate triangular structure with a Cu-N bond length of 201 pm. Such a decrease in the coordination number was interpreted in terms of the bulk
