Synthesis of α-halo β,γ-unsaturated esters from γ-phenylseleno α,β-unsaturated esters

Article abstract of DOI:10.1016/S0040-4039(00)60141-7

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.
