promoted by the same boron catalyst. Benzene and dihydrogen are formed during the reaction, but no salt waste is. This expedient protocol is applicable to several silicon groups, and the preparation of trimethylsilyl ethers presented here is potentially useful for alcohol derivatization prior to GLC analysis.
描述了由强路易斯酸 B(C6F5)3 催化的前所未有的醇转移硅烷化反应。气态 Me3SiH 由 B(C6F5)3 催化分解 3-三甲基甲硅烷基环己-1,4-二烯原位释放,随后与醇在相同硼催化剂促进的脱氢 Si-O 偶联中反应。在反应过程中形成苯和二氢,但没有盐废物。此权宜之计适用于多个硅基团,此处介绍的三甲基甲硅烷基醚的制备对于 GLC 分析之前的醇衍生化可能有用。
