(Trimethylsilyl)methyl chloride

(Trimethylsilyl)methyl chloride is the organosilicon compound with the formula (CH3)3SiCH2Cl. A colorless, volatile liquid, it is an alkylating agent that is employed in organic synthesis, especially as a precursor to (trimethylsilyl)methyllithium. In the presence of triphenylphosphine, it olefinates benzophenones:
 * (CH3)3SiCH2Cl + PPh3  +  Ar2C\dO  →  Ar2C\dCH2  +  OPPh3  +  (CH3)3SiCl
