A new reagent system, phenyl trimethylsilyl selenide-aluminum bromide, was developed for the direct conversion of various benzylic hydroxy groups into a selenenyl group. Treatment of cinnamyl alcohol with this reagent system yielded 3, 4-dihydro-4-phenyl-2H-1-benzoselenin via a [3, 3]-sigmatropic rearrangement of the intermediate cinnamyl phenyl selenide.
开发了一种新试剂体系,苯基三甲基甲硅烷基硒化物-溴化铝,用于将各种苄位羟基直接转化为硒烯基。用这种试剂体系处理肉桂醇,通过中间体肉桂基苯基硒化物的[3,3]-σ迁移重排,生成了3,4-二氢-4-苯基-2H-1-苯并硒英。
