An　efficient　and　convenient　synthetic　methodology　has　been　developed　with　which　to　construct　β-trifluoromethylthio-　and　seleno-α,β-unsaturated　ketones　through　copper-mediated　trifluoromethylthio(seleno)lation　of　β-bromo　α,β-unsaturated　ketones.　The　corresponding　ketone　products　were　isolated　in　moderate　to　good　yields　and　were　efficiently　converted　into　valuable　alcohols.　©　Georg　Thieme　Verlag.
