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.
