Intermolecular Insertion of Ethylene and Octene into a Palladium-Amide Bond. Spectroscopic Evidence for an Ethylene Amido Intermediate

摘要

Additions to olefins comprise some of the most utilized catalytic reactions. Many of these reactions occur by transfer of a hydride or an alkyl group from a transition-metal complex to a coordinated alkene in a reaction commonly termed migratory insertion. Migratory insertion of an olefin into a transition metal-amide bond is much less established but has been proposed to occur during several classes of palladium-catalyzed reactions, including carboaminations, oxidative aminations, diaminations, aminoacetoxylations, chloroaminations, and hetero-Heck type transformations.
