reagent and a single‐electron transfer (SET) reagent in the reaction of α‐halo, γ‐halo‐α,β‐unsaturated ketones and esters with allylsamarium bromide is reported for the first time in this paper. From a synthetic point of view, a general, efficient and experimentally simple one‐pot method for the preparation of 1,4‐dienes and trienes is developed. A possible mechanism of the transformation is proposed.
首次报道了烯丙基溴化溴作为亲核试剂和单电子转移(SET)试剂在α-卤代,γ-卤代-α,β-不饱和酮和酯与烯丙基溴化reaction的反应中的用途在本文中。从综合的角度出发,开发了一种通用,高效且实验简单的一锅法制备1,4-二烯和三烯的方法。提出了一种可能的转化机制。
