Abstract
Chemical transformations have been studied of nitromethyl group in 3,5-dicyano-1,4,4,6-tetramethyl-2-nitromethyl-1,4-dihydropyridine (I) brought about by action of acetic acid and/or acetic anhydride, diazomethane, and phosphorus trichloride and giving also the products VIII and IX of intramolecular reaction with the neighbouring cyano group. Spectral characteristics of the synthetized compounds and their splitting by electron impact in mass spectrometer are given, and mechanism of the individual transformations is discussed.
