Pivalophenone N-H imine has been found to serve as a prominent substrate for directed C-H alkylation and arylation reactions with alkyl bromides and aryl chlorides, respectively, under cobalt-N-heterocyclic carbene (NHC) catalysis. Unlike the case of the parent pivalophenone imine, the increased steric bulk of the resulting ortho-substituted pivalophenone imines allows them to undergo clean imine-to-nitrile conversion under peroxide photolysis or aerobic copper catalysis conditions. Overall, these two-step transformations offer convenient synthetic methods for ortho-functionalized benzonitriles.
