3‐Aryl‐1,2,4‐benzotriazines were conveniently prepared in moderate to good yields from 1,l‐bis(benzotriazol‐1‐yl)methylarenes with allylsamarium bromide/hexamethylphosphramide (allylSmBr/HMPA). Preliminary results indicate that HMPA may enhance the reducing ability as well as prohibit the nucleophicility of allylSmBr, thus making allylSmBr/HMPA as a promising single‐electron transfer (SET) reagent
由1,l-双(苯并三唑-1-基)甲基芳烃与烯丙基溴化//六甲基磷酰胺(allylSmBr / HMPA)制备中度到良好收率的3-芳基1,2,4-苯并三嗪很方便。初步结果表明,HMPA可能增强烯丙基SmBr的还原能力,并阻止其烯键性,因此使烯丙基SmBr / HMPA成为有前途的单电子转移(SET)试剂。
