In transition metal-mediated carboxylation reactions, CO2 inserts into a metal-nucleophile bond. At the carboxylation transition state (TS), CO2 may interact with the metal (inner-sphere path) or may insert without being activated by the metal (outersphere path). Currently, there is no consensus as to which path prevails. In order to establish general predictions for the insertion of CO2 into metal-carbon bonds, we computationally analyze a series of experimentally reported Cu, Rh, and Pd complexes. Our focus is on carboxylation of aromatic substrates, including C(sp)(3 )benzyl and C-sp(2) aryl and alkenyl nucleophiles. We observe clear trends, where the nature of the nucleophile determines the preferred path: benzylic C-sp(3), nucleophiles favor outer-sphere and C-sp, systems favor inner-sphere CO2 insertion into the metal-carbon bond. An exception are Cu-benzyl bonds, where inner- and outer-sphere CO2 insertions are found to be competitive, highlighting the need to include both paths in mechanistic studies and in the rationalization of experimental results. For insertion into Pd-C-sp2 bonds, we find that the metal-CO2 interactions at the TS are weak and may be beyond 3 angstrom for sterically congested ligands. Nonetheless, on the basis of a comparison to other TSs, we argue that the CO2 insertion into Pd-C(sp2 )bonds should be classified as inner-sphere.
