Abstract

Abstract A wide variety of alcohols and phenols were protected as trimethylsilyl ethers using 1, 1, 1, 3, 3, 3-hexamethyl disilazane catalyzed by aspartic acid as a non-toxic, metal-free, and green organocatalyst at room temperature in acetonitrile under mild and heterogeneous conditions. The procedure is operationally simple and the silylated product was obtained in high yield and purity.
