metal-catalyzed protocol for the sequential multiarylation of cyclic allyl sulfones is described. The metal-coordinating ability of the 2-pyridyl group on the sulfone promotes the otherwise difficult intermolecular Heck monoarylation and diarylation of trisubstituted alkenes, as well as the copper-catalyzed allylicarylation with Grignard reagents.
