Abstract

Abstract Nitration of polyalkyated 3, 5-dicyano-1, 4-dihydropyridines Ia-Id to the first and second degrees has been studied leading to compounds II and III, and conversion of nitromethyl groups of these compounds into nitrile groups with formation of tricyano derivatives IV and tetracyano derivatives V has been followed. Also given is the fragmentation of the synthesized compounds II-V by an electron impact in mass ...
