Trichloroisocyanuric acid (TCCA) as a mild and efficient catalyst for the trimethylsilylation of alcohols and phenols with hexamethyldisilazane (HMDS) under heterogonous conditions

A novel and efficient method for the trimethylsilylation of various alcohols and phenols with hexamethyldisilazane (HMDS) catalyzed by trichloroisocyanuric acid (TCCA) in good to excellent yields in dichloromethane at room temperature was described.
