TMSCl is reactive toward nucleophiles, resulting in the replacement of the chloride. In a characteristic reaction of TMSCl, the nucleophile is water, resulting in hydrolysis to give the hexamethyldisiloxane: 2 Me3SiCl + H2O → Me3Si-O-SiMe3 + 2 HCl The related reaction of trimethylsilyl chloride with alcohols can be exploited to produce anhydrous solutions … A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry. This group consists of three methyl groups bonded to a silicon atom [−Si(CH3)3], which is in turn bonded to the rest of a molecule.
