Abstract
Symmetrical N,N1-disubstituted formamidines of formula R-NH-CH=N-R, in which R represents alkyl radicals, aralkyl radicals, or alkyl and aralkyl radicals substituted with dialkylamino groups containing 1 to 4 carbon atoms in the alkyl radical, alkoxy groups containing 1 to 4 carbon atoms, nitrile or hydroxy groups, are prepared by mixing an amine of formula R-NH2 with hydrogen cyanide in a molar ratio of at least 2: 1 at a temperature of from 50 DEG to 135 DEG C. until no more ammonia is liberated, and then distilling the reaction mixture. The process may be carried out in an inert solvent.
