title: Improved yields with added copper(I) salts in carbonylative stille couplings of sterically hindered vinylstannanes.
abstract: Stille coupling under standard carbonylative conditions proceeds in poor yield when using hindered alkenylstannane and enol triflate partners. The inclusion of 35 mol % CuI or CuBr significantly improves the efficiency of the coupling, providing a variety of complex 1,4-dien-3-ones in good to excellent yield.
