Abstract

Chloro-olefins which contain a group of the formula ##STR1## where Y is chlorine or hydrogen, which are prepared by a process in which a trichloromethyl compound which contains a group of the general formula ##STR2## where X is hydrogen or an organic radical, is reduced with a chromium(II) salt in an aqueous medium.
