γ-Phenylseleno α,β-unsaturated esters, prepared from α-phenylseleno aldehydes by Horner-Emmons reaction and treated with bromine or sulfuryl chloride, form adducts whose decomposition leads to α-halo β,γ-unsaturated esters in fair to good yields.
由Horner-Emmons反应由α-苯基硒代醛制备并经溴或磺酰氯处理的γ-苯基硒代α,β-不饱和酯形成加合物,其分解可导致α-卤代β,γ-不饱和酯以相当高的收率获得。
