4-palladium migration/ring-opening C–C cleavage cascade, giving trisubstituted alkenes in high yields. The protocol features good regioselectivity, high yields, broad substrate scopes, and good functional group tolerance. The mechanistic studies implicate that the cross-coupling reaction occurs via oxidative addition, 1,4-palladium migration, ring-opening C–C cleavage, and reductive elimination. DFT calculations

efficient Pd-catalyzed arylative ring expansion of cyclobutanols viaC–Cbondcleavage is presented. The method allows the coupling of aryl chlorides at low catalyst loadings with a wide range of functional groups and substitution patterns, thus constituting a straightforward alternative for preparing rather elusive γ-arylatedketones.
