The Stille coupling of (E)-stannyl-unsaturated esters with alkynyl bromides in DMF in the presence of Pd(PPh3)4 and CuI gave (Z)- 2-ethoxycarbonyl-1,3-enynes in good yields. The latter underwent the palladium-catalysed hydrostannylation with tributyltin hydride in THF at room temperature to afford (1E,3E)-2-ethoxycarbonyl-3- stannyl-1,3-dienes in good yields with high regio- and stereoselectivities.

Palladium-catalysed hydrostannylation of alkynyl esters in benzene at room temperature gives regio- and stereoselectively (E)-α-stannyl-α, β-unsaturated esters in good yields. (E)-α-Stannyl-α,β;- unsaturated ethyl esters are difunctional group reagents wh
