The synthesis of the fluoromethyltrimethylsilanes 4 <(H3C)3SiCF2X, 4a: X=Cl; 4b: X=Br; 4c: X=H; (H3C)3SiCFXY, 4d: X=Cl; Y = H; 4e: X, Y=H>> is described.The reaction of the tris-(diethylamino)-phosphane (1)/trimethylsilylhalogenide 3 system with the difluorodihalogenomethanes 2 gives the hitherto unknown 4a,b.The reduction of 4a,b and dichlorofluoromethyltrimethylsilane (13) <(H3C)3SiCFCl2> with tris-(n-butyl)stannane (14) produces 4c-e in fair yields.
