A method for preparing (trichloromethyl)organosilanes by the catalytic decarboxylation of the corresponding trichloroacetoxysilanes RMe2SiOC(O)CCl3 (R=Me, ClCH2, Ph, Me3Si, and H) has been developed.The method involves heating the starting compounds without a solvent in the presence of a catalyst (quaternary ammonium salts or potassium salts with the addition of crown ethers).Tertiary amines (Et3N, Bu3N) catalyze this reaction only when heating is carried out in donor aprotic solvents (THF, acetonitrile) in the presence of oxygen.Thermal decomposition of (trichloroacetoxy)organosilanes, in contrast to catalytic decarboxylation, begins at a higher temperature and yields a mixture of products.Key words: organosilanes, trichloroacetoxy and trichloromethyl derivatives; catalytic decarboxylation.

Polychloromethylation of Me3SiCl, Me2PhSiCl, Me2SiCl2, and MePhSiCl2 in the system magnesium-chloroform-THF has been studies under mild conditions (in the temperature renge 60 -65 deg C), and a scheme of formation of the main and by-products has been proposed.
