The aluminum chloride-catalyzed acylation of α-silylallylic selenides with acid chlorides at −78 °C produced γ-acylated vinylic selenides regioselectively. α-Silylallylic selenides in some cases underwent [1,3] shifts of the selenenyl groups by the catalysis with aluminum chloride, affording γ-silylallylic selenides. This regioselective acylation of allylic selenides provides a new route to dihydrojasmone
氯化铝催化的α-甲硅烷基烯丙基硒化物与酰基氯在-78°C 的酰化反应区域选择性地产生了γ-酰化的乙烯基硒化物。在某些情况下,α-甲硅烷基烯丙基硒化物在氯化铝的催化下经历了硒基的 [1,3] 位移,得到 γ-甲硅烷基烯丙基硒化物。这种烯丙基硒化物的区域选择性酰化为二氢茉莉酮提供了一条新途径。
