Abstract: The treatment of activated alkynes with catalytic amounts of Stryker's reagent and tributylstannane resulted in hydrostannation. The reaction proceeds with high regioselectivity to produce α-stannated vinylstannanes exclusively.
Keywords: copper; regioselectivity; vinylstannanes; alkynes; hydrostannation.
