Rh(acac)(CO)2 catalyzes addition of (N,N-diisopropylcarbamoyl)trimethylstannane to terminal alkynes to give (Z)-β-stannyl-α,β-unsaturated amides with terminal attachment of the amide group, while the use of Ni(cod)2 results in the reversal of the regioselectivity. A mechanism initiated by the oxidative addition of the carbamoylstannane was proposed on the basis of the isolation of (trimethylstannyl)(N,N-diisopropylcarbamoyl)[1, 2-bis(dimethylphosphino)ethane]palladium.
