Abstract
The palladium-catalyzed desilylation-arylation of substituted vinylsil anes by p-iodoanisole in the presence of bidentate phosphine ligands i s described. Apart from enhancing the rate of the reaction considerabl y, heteroatom-based functional groups in the vinylsilane moiety have a profound influence on the regiochemistry. A catalytic cycle for the c helation-controlled desilylation-arylation reaction involving five- an d six-membered chelate rings is proposed.
