摘　　要：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.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.
