(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:^[2]

(CH₃)₃SiCH₂Cl + PPh₃ + Ar₂C=O → Ar₂C=CH₂ + OPPh₃ + (CH₃)₃SiCl
