(Trifluoromethyl)trimethylsilane, CF3SiMe3 reacts with [(Me2N)3S]+[Me3SiF2]-, Q+F- and Q+[HF2]-(Q+ = Me4N+, [(Me2N)3C]+, [(Me2N)4P]+) at -70 to 50°C to afford the first hypervalent silicon species, [(CF3)2SiMe3]- with five Si-C bonds (stable in monoglyme up to -10°C) as the main reactive species whose molecular structure was determined by X-ray crystallography.

Tetramethylchloroformamidinium chloride reacts with 2mol equivalents of tetramethylammonium fluoride to give bis(dimethylamino)difluoromethane (1). The treating of 1 with dimethylaminotrimethylsilane in acetonitrile yields quantitatively hexamethylguanidinium fluoride (2). Reaction of 2 with (trifluoromethyl)trimethylsilane provides an easy access to 1,1,1-trifluoro-2,2,2-tris(dimethylamino)ethane (4).
