1,1-Bis(R-phenyl)-2,2,2-trichloroethanes are dehydrochlorinated in high yields, e.g., into 1,1-bis(chlorophenyl)-2,2-dichloroethylenes, by reacting same with an aqueous solution of an alkali metal hydroxide, in liquid state in the presence of a phase transfer agent, e.g., a quaternary ammonium compound, but in the absence of any reaction solvent.
