Cyclocondensation of 3-aryl-2-benzylidene-3-oxopropanenitriles Ia and Ib with acetyl aromatic derivatives IIa-IIc in the presence of ammonium acetate affords 2,6-diaryl-4-phenyl-3-cyanopyridines IV and V. Reaction of the nitrile Ib with 1,2-diphenylethanone (III) gave 2-(4-biphenylyl)-4,5,6-triphenyl-3-cyanopyridine (VI). The relation between the structure of the synthesized pyridine derivatives IV-VI and their spectral properties is discussed.

Abstract:
The Al coatings were electrodeposited on the Cu substrate from AlCl3-EMIC ionic liquid (AlCl3:EMIC = 2:1 molar ratio) containing three cyanopyridine additives with different positions of the substituent group on the pyridine ring, which were 2-cyanopyridine, 3-cyanopyridine, and 4-cyanopyridine. The effects of cyanopyridine additives on the deposition potential, morphology, brightness, and corrosion properties of Al coatings were investigated. It was considered that the deposition potential of Al shifted to more negative overpotentials, the quality of Al coatings was promoted, and the corrosio

Abstract:
Abstract The formation of cyanopyridine (CN-py) adducts of silicon tetrahalides was investigated for 3- and 4-cyanopyridine in combination with SiF4 and SiCl4. Whereas bubbling of SiF4 through toluene solutions of 3-CN-py and 4-CN-py afforded white precipitates, which should possess the respective composition SiF4(CN-py)2, addition of SiCl4 did not cause any precipitation. Upon storage of the toluene solution of SiCl4 and 4-CN-py at 6 °C for several weeks, some crystals of the composition SiCl4(4-CN-py)2 ⋅ 2 (4-CN-py) ⋅ (toluene) were obtained.

The reaction of iron thiocyanate with 3-cyanopyridine (C6H4N2) leads to the formation of two compounds with the composition [Fe(NCS)2(C6H4N2)4] (1) and [Fe(NCS)2(C6H4N2)2(H2O)2]·2C6H4N2 (2). The asymmetric unit of 1 consists of one iron cation, two thiocyanate anions and four 3-cyanopyridine ligands in general positions. The iron cation is octahedrally coordinated by two N-bonded thiocyanate anions and four 3-cyanopyridine ligands. The complexes are arranged in columns along the crystallographic c-axis direction and are linked by weak C—H...N interactions. In 2, the asymmetric unit consists of
