The reaction of acetylenedicarboxylic acid and propiolic acid with tributyltin hydride efficiently yields vinylic tin compounds bis(tributylstannyl) 2-tributylstannylbutenedioates (E/Z,1:20) and tributylstannyl 3-tributylstannylacrylates (E/Z,1:1), respectively, with regiochemistry similar to that seen in the reaction of the corresponding esters.
