(E) and (Z)-chloroenynes undergo rapid addition of tributyltin hydride in the presence of a catalytic amount of palladium complex to give regio- and stereoselectively chlorodienyl stannanes of general formula A in good to excellent isolated yields. Hydrostannation of conjugated (Z)-1,3-enynes has also been performed and showed to be remarkably regioselective.
