An ethylenic hydrocarbon is reacted with carbon tetrachloride in the presence of an alkyl phosphite, an iron chloride and a nitrile compound. According to this process, tetrachloroalkanes having more than two carbon atoms can be obtained in high yields.

Process for the preparation of tetrachloroalkanes

Fluoroalkylsilanes of the general formula R'CH.sub.2 CH.sub.2 SiR.sub.n X.sub.3-n are prepared by reaction of an organohydrogensilane of the general formula R.sub.n SiHX.sub.3-n with a fluoroolefin of the general formula R'CH.dbd.CH.sub.2, where R is an alkyl or aryl group, R' is a perfluoroalkyl group, X is a halogen atom or an alkoxy group and n is 0, 1 or 2 in the presence of a binary catalyst composed of a platinum compound and stannous chloride under relatively mild conditions of temperature and pressure, at a very high yield.
