Fluoroalkylsilanes of the general formula R'CH2CH2SiRnX3-n are prepared by reaction of an organohydrogensilane of the general formula RnSiHX3-n with a fluoroolefin of the general formula R'CH=CH2, 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. |
