Nano silica supported sodium hydrogen sulfate has been prepared by mixing NaHSO4 with activated Nano silicagel. We wish to report a new method for the synthesis of trimethyl (TMS), triethyl (TES) and t‐butyldimethyl silyl (TBS) ethers from benzylic, allylic, propargylic alcohols, phenols, naphtholes and some of phenolic drugs in the solution and under solvent‐free conditions.
通过将NaHSO 4与活化的纳米硅胶混合,制备了纳米二氧化硅负载的硫酸氢钠。我们希望报告一种在溶液中和溶液中由苄基,烯丙基,炔丙醇,酚,萘酚和某些酚类药物合成三甲基(TMS),三乙基(TES)和叔丁基二甲基甲硅烷基(TBS)醚的新方法无溶剂条件。
