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.
在室温下的二氯甲烷和无溶剂条件下,使用一定量的 N-溴代琥珀酰亚胺催化剂,通过与六甲基二硅氮烷(HMDS)进行清洁高效的反应,实现了结构多样的醇和酚的三甲基硅烷化。在催化量 NBS 的存在下,在室温下的甲醇中也能有效地实现三甲基硅基醚的脱保护:N-溴代丁二酰亚胺、无溶剂、醇、酚、六甲基二硅氮烷、三甲基硅基醚、催化剂、去甲基硅烷化。
