Rapid and highly efficient trimethylsilylation of alcohols and phenols with hexamethyldisilazane (HMDS) catalysed by in situ generated I 2 using Oxone®/KI or cerium ammonium nitrate (CAN)/KI systems under mild conditions

摘要

Structurally diverse alcohols and phenols were trimethylsilylated in clean and efficient reactions with hexamethyldisilazane (HMDS) in the presence of a catalytic amount of I2 generated in situ from Oxone®/KI or CAN/KI systems. The reactions occur rapidly in good to high yields in wet CH2Cl2 at room temperature.
