简介 Trimethylsilylacetylene is an acetylene molecule protected on one end by the trimethylsilyl group. It is popularly used in alkynylations, e.g. the Sonogashira reaction. After desilylation (e.g. with TBAF), the ethynyl group is introduced. Using a protected alkyne, as opposed to acetylene gas, prevents further (undesired) coupling reactions and also has the benefit of being a liquid. This compound is commercially available. It may also be prepared in a manner similar to other silyl compounds: deprotonation of acetylene with a Grignard reagent, followed by reaction with trimethylsilyl chloride. 基本信息 中文名称 三甲基乙炔基硅 英文名称 Ethynyltrimethylsilane 中文别名 三甲基硅基乙炔; (三甲基硅烷基)乙炔; 三甲基硅乙炔; 三甲硅基乙炔; (三甲基甲硅烷基)乙炔; 查看更多中文别名 英文别名 ethynyl(trimethyl)silane; (Trimethylsilyl)Acetylene; TriMethylsilylacetylene; CAS号 1066-54-2 分子式 C5H10Si
