Reactions of 2-ethoxymethylidene derivatives of 1,3-dicarbonyl compounds with N,N-dimethylethane-1,2-diamine gave a number of 2-[(2-dimethylaminoethyl)amino]methylidene-1,3-dicarbonyl compounds which were subjected to regioselective quaternization at the tertiary nitrogen atom with methyl iodide. The resulting quaternary ammonium salts inhibited aggregation of cadmium and zinc sulfide sols in aqueous medium.
