The palladium catalyzed hydroesterification of acenaphthylene takes place through a “hydride” mechanism, that is, through the selective cis insertion of the olefin into the palladium–hydride bond, an obvious prerequisite for the successful development of an enantioselective version of the reaction; however, a degenerate substitution equilibrium between Pd0Ln and the PdII-alkyl species, involving the inversion of the alkyl carbon, is ...
