Abstract

Process for the preparation of 1-methyl-1,2-di- [benzimidazolyl- (2 ')] - ethylene compounds of the formula ** (See formula) ** in which A1 and A2 each represent a benzene radical, of which 2 neighboring cyclic carbon atoms belong at the same time to the imidazole ring, and X and Y each mean the complement of an imidazoic radical, characterized in that, at temperatures above 150º C and in the presence of phosphoric acids of the formula Hn+2PnO3n+1 where n means an integer, a dicarboxylic acid of the formula is reacted in the molecular ratio 1: 2 ** (See formula) ** wherein C3H4 means a radius to the single unsaturated hydrocarbon and the two carboxylic acid groups are linked to neighboring carbon atoms of the C3H4 radical, or a functional derivative of an acid of this nature, with at least one 1,2-diaminobenzene of which one amino group is primary, while the other amino group is at most secondary.
