variety of alcohols, including primary, benzylic, secondary, and phenols with hexamethyldisilazane, has been developed. The reactions were carried out at room temperature in the presence of a catalytic amount of niobium(V) chloride and afforded the corresponding trimethylsilyl ethers in high to excellent yields in short time. GRAPHICAL ABSTRACT
摘要 已经开发了一种高效、方便的方法,用于使用六甲基二硅氮烷对包括伯醇、苄醇、仲醇和酚在内的多种醇进行三甲基硅烷化。该反应在室温下在催化量的氯化铌 (V) 存在下进行,并在短时间内以高至极好的收率提供相应的三甲基甲硅烷基醚。图形概要
