Propargylic ethers and acetates can be converted into distannylated alkenes in the presence of Bu 3 SnH and a Pd catalyst. The reaction proceeds via a stannylated allyl alcohol derivative, which undergoes elimination and subsequent dimetalation. If a molybdenum catalyst is used in the hydrostannylation step, and the stannylated intermediates can be reacted with other dimetallic compounds.
