safe, high-yielding and rapid microwave-assisted method for the preparation of protected p-bromomethyl and p-dibromomethylanilines was developed as new alcohol, thiol, and amine protection groups. The procedure involves microwave-assisted N-bromosuccinimide (NBS) radical bromination of readily available N-protected p-toluidine. The microwave-assisted radical bromination was found to be superior to the
摘要 开发了一种简单、高效、安全、高产、快速的微波辅助制备受保护的对溴甲基和对二溴甲基苯胺作为新型醇、硫醇和胺保护基团的方法。该过程包括微波辅助 N-溴代琥珀酰亚胺 (NBS) 自由基溴化现成的 N-保护对甲苯胺。发现微波辅助自由基溴化优于传统的 NBS 自由基溴化。
