Abstract

PURPOSE: To prepare the title compound useful as an intermediate of pharmaceuticals, pesticides, dyes and pigments, directly, economically, in high yield and in an industrial scale, by reacting diaminomaleonitrile with cyanogen halide in the presence of water.
CONSTITUTION: 2-Amino-4,5-dicyanoimidazole of formula is prepared by reacting diaminomalenitrile (1 part by weight) with a cyanogen halide (pref. cyanogen chloride or cyanogen bromide) in the presence of water (usually 2W200 parts, pref. 5W100 parts by weight). The reaction is pref. carried out first by preparing an aqueous solution of a cyanogen halide by the reaction of an aqueous solution of an alkali cyanide such as sodium cyanide, potassium cyanide, etc., with a halogen, and then reacting the solution with diaminomaleonitrile.
