Nickel-Catalyzed Activation of Acyl C-O Bonds of Methyl Esters

摘要

We report the first catalytic method for activating the acyl C-O bonds of methyl esters through an oxidative-addition process. The oxidative-addition adducts, formed using nickel catalysis, undergo in situ trapping to provide anilide products. DFT calculations are used to support the proposed reaction mechanism, to understand why decarbonylation does not occur competitively, and to elucidate the beneficial role of the substrate structure and the Al(OtBu)(3) additive on the kinetics and thermodynamics of the reaction.
