Description and Uses
Triphenylsilyl chloride is a white to off-white crystal or powder with acrid ordor of hydrogen chloride, used for synthesis of pharmaceutical intermediates.
A wide variety of Grignard reagents and organolithium complexes participate in reactions with Ph3SiCl to afford organosilanes. Thus the reaction of allylmagnesium chloride with Ph3SiCl gives the allylsilane in high yield (eq 3).However, when hydrosilyl Grignard reagents are employed, reduction to the silane occurs (eq 4).Azaallyl anion6 and diazolithium salts can each be silylated to give the anticipated silane adducts (eqs 5 and 6). Similarly, arylsilanes8 and alkynylsilanes are produced upon silylation of the appropriate metalated13 carbanions with Ph3SiCl (eqs 7–11).
