摘  要:An efficient procedure for the trimethylsilylation of alcohols and phenols is presented.The combination of 1,1,1,3,3,3-hexamethyldisilazane and a catalytic amount of phenyltrimethylammonium tribromide(PhMe3N+Br3?) was found to be effective for the trimethylsilylation of alcohols and phenols.The protection reaction is very simple and homogenously performed in dichloromethane at room temperature and mild conditions.An efficient procedure for the trimethylsilylation of alcohols and phenols is presented.The combination of 1,1,1,3,3,3-hexamethyldisilazane and a catalytic amount of phenyltrimethylammonium tribromide(PhMe3N^+Br3^-) was found to be effective for the trimethylsilylation of alcohols and phenols.The protection reaction is very simple and homogenously performed in dichloromethane at room temperature and mild conditions.
