Synthesis, X-ray and spectroscopic analysis of some pyridine derivatives
Three pyridine derivatives, 4-(methoxymethyl)-6-methyl-2-oxo-1, 2-dihydropyridine-3-carbonitrile (1), 4-(methoxymethyl)-6-methyl-5-nitro-2-oxo-1, 2-dihydropyridine-3-carbonitrile (2) and 4-(methoxymethyl)- 1, 6-dimethyl-2-oxo-1, 2-dihydropyridine-3-carbonitrile (3) have been synthesized, and their structural features have been studied by IR and electronic spectroscopy. The optical properties were investigated by UV–vis absorption and fluorescence spectroscopy. Fluorescence spectra of compounds have been recorded in two protic and two aprotic solvents in the range of 200–600 nm. The effects of substituents on the emission spectra of these compounds are interpreted. The structures of compounds 2 and 3 were also confirmed by single crystal X-ray diffraction method.
