Structurally diverse alcohols and phenols were trimethylsilylated in a clean and efficient reaction with hexamethyldisilazane (HMDS) based on the use of a catalytic amount of N-bromosuccinimide under both dichloromethane and solvent-free conditions at room temperature. Deprotection of trimethylsilyl ethers was also be achieved efficiently in the presence of a catalytic amount of NBS in methanol at ambient temperature.Key words: N-bromosuccinimide, solvent-free, alcohols, phenols, hexamethyldisilazane, trimethylsilyl ether, catalyst, detrimethylsilylation.
