Triphenylsilyl chloride Chemical Properties,Uses,Production

?Acute toxicity

IV- mouse LD50: 56 mg/kg

Description

Triphenylsilyl chloride is a white to off-white crystal or powder with acrid ordor of hydrogen chloride, used for synthesis of pharmaceutical intermediates.

Physical properties

mp 92–94°C; bp 240–243°C/35 mmHg.

Uses

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).silylation

Uses

Chlorotriphenylsilane is used as a silylating agent. It is also used as a pharmaceutical intermediate.

Purification Methods

Likely impurities are tetraphenylsilane, small amounts of hexaphenyldisiloxane and traces of triphenylsilanol. Purify it by distillation at 2mm, then crystallise it from EtOH-free CHCl3, and from pet ether (b 30-60o) or hexane by cooling in a Dry-ice/acetone bath.
