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 amides of DAMN. Tetrasubstituted pyrazines are prepared by condensation of DAMN with diimines prepared from alcohols and cyanogen.
