Iron-catalyzed ortho C?H arylation and methylation reactions of pivalophenone N?H imines are reported. The pivaloyl N?H imine proved an excellent directing group for the arylation with diarylzinc reagents in the presence of an iron-diphosphine catalyst an

A cobalt-catalyzed ortho-C-H benzylation reaction of pivalophenone N-H imines with benzyl phosphates is reported. The reaction is promoted at room temperature by a ternary catalytic system comprising Co(acac)3, a pyridylphosphine ligand, and a Grignard reagent and tolerates a series of substituted pivalophenone imines and benzyl phosphates to afford various diarylmethane derivatives in moderate yields.
