摘要

Process for the preparation of diphenylnylkeneic acids of formula = formula ** (wherein r represents hydrogen, or an alkyl radical) characterized in that the 4-diphenylyl-acetonitrile is treated, optionally after a previous alcoholysis operation, with the halide of an unsaturated hydrocarbon, to introduce the chain of said hydrocarbon to the carbon atom bound to the diphenyl nucleus and then the intermediate product thus obtained is subjected to a hydrolysis treatment.
