Abstract

Alkyl derivatives of diaminomaleonitrile (DAMN), are prepared by direct methylation and by reduction of Schiff bases. Cyclic anhydrides and DAMN produce amide acids. 2, 3- Dicyanodiazepines and 2, 3-dicyanodihydrodiazepines are prepared by condensation of DAMN with 1, 3-diketones or other carbonyl derivatives. 2-Substituted 4, 5- dicyanoimidazoles are prepared by improved cyclization procedures of Schiff bases and ...
