A sequential, palladium-catalyzed, stereoselective disubstitution of 1,1-dibromoalkenes with various alkenyltrifluoroborates followed by alkyltrifluoroborates proceeds smoothly in one pot under mild reaction conditions to provide the corresponding trisubstituted, conjugated dienes in excellent yield.
