A protocol for copper-catalyzed halogen exchange/C−P cross-coupling between (cyclo)alkenyl/arylbromides and secondary phosphine oxides has been developed. The addition of sodium iodide increases the yield of the cross-coupling by promoting in situ halogen exchange of organic bromides to the corresponding iodides.
