Abstract An easy preparation of trimethylsilyl ethers of alcohols and phenols with 1,1,1,3,3,3-hexamethyldisilazane(HMDS) catalysed by montmorillonite K-10 at room temperature has been carried out in excellent yields. Desilyation of trimethylsilyl ethers is catalysed by K-10 in methanol at ambient temperature in high yields.
摘要 以蒙脱石 K-10 为载体,在室温下以 1,1,1,3,3,3-六甲基二硅氮烷 (HMDS) 为原料制备了醇和酚的三甲基甲硅烷基醚,收率良好。三甲基甲硅烷基醚的脱甲硅烷基化反应在室温下由甲醇中的 K-10 以高产率催化。
