Abstract

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.

Study Snapshot

Nano silica supported sodium hydrogen sulfate effectively catalyzes the synthesis of trimethyl, triethyl, and t-butyldimethyl silyl ethers from aliphatic and aromatic alcohols under solvent-free conditions.
