2025年1月27日 · Related to the epoxide ring opening, TMSCl also mediates some cyclopropane ring opening reactions.

Trimethylsilyl chloride (TMSCl) is a commonly used silylating agent that can be employed to temporarily protect alcohols in organic chemistry. By reacting an alcohol with TMSCl, a silyl ether is formed, which masks the reactivity of the hydroxyl group.

TMSCl afforded b-acetamido carbonyl compounds with high dia-stereoselectivity.7 (H) A range of allylic alk-3(2)-enoates in the presence of DBU (1,8-diazabicycl[5.4.0]undec-7-ene) and an excess amount of TMSCl un-der reflux in acetonitrile underwent an Ireland–Claisen [3,3] rear-rangement to yield 2-ethylidene g,d-unsaturated carboxylic acids

TMSCl, or trimethylsilyl chloride, is a common silylating agent used in organic chemistry, particularly in the context of protecting alcohols. It is a volatile, colorless liquid that is widely employed in various synthetic transformations to introduce a trimethylsilyl (TMS) protecting group.
