The strategic generation and interception of palladium-hydrides for use in alkene functionalization reactions

Abstract

Abstract We review methods that our lab has developed for the generation of Pd-hydrides and the manipulation of these useful intermediates via β-hydride elimination and migratory insertion steps. For a given alkene functionalization reaction, careful understanding of the dynamics of β-hydride elimination, migratory insertion, and transmetallation have allowed for the selective functionalization of Pd-alkyl intermediates. This has afforded us a means by which to transpose palladium to a desired position on a substrate for subsequent functionalization, empowering a number of useful C–H, C–O, and C–C bond-forming reactions.
