摘要：

Vinyl triflates couple smoothly with a variety of arylstannanes provided a polar, aprotic solvent is used in conjunction with a ''ligandless'' palladium catalyst, or a catalytic system involving weak ligands such as triphenylarsine. Commonly employed ligands, for example, triphenylphosphine, were found to strongly inhibit the coupling.
