Formation of homoallyl stannanes via palladium-catalyzed stannylative cyclization of enynes
[reaction: see text] Treatment of 1,6-enynes with tri(n-butyl)tin hydride in the presence of a catalytic amount of palladium acetate leads to the formation of exo-methylenecyclopentanes bearing a tri(n-butyl)stannylmethyl moiety.
