containing functional groups on silicon, is described. The new preparative procedure involves treatment of α-ethoxyvinyllithium with a halosilane to give an α-silyl enol ether, which is hydrolyzed under mild conditions to give the corresponding acetylsilane. Bulky t-butyl groups on silicon can be used to protect a reactive fluorine substituent during the hydrolysis step.
描述了乙酰二叔丁基硅烷和乙酰二叔丁基氟硅烷的制备,乙酰二叔丁基氟硅烷是在硅上含有官能团的第一稳定的酰基硅烷。新的制备方法涉及用卤代硅烷处理α-乙氧基乙烯基锂,得到α-甲硅烷基烯醇醚,将其在温和条件下水解,得到相应的乙酰基硅烷。硅上的大叔丁基可用于在水解步骤中保护反应性氟取代基。
