Direct Comparison of C-H Bond Amination Efficacy through Manipulation of Nitrogen-Valence Centered Redox: Imido versus Iminyl

Reduction of previously reported iminyl radical (L-Ar)FeC1(center dot N(C6H4-p-Bu-t)) (2) with potassium graphite furnished the corresponding high-spin (S = 5/2) imido (L-Ar) F e (N(C6H4-p-Bu-t)) (3) (L-Ar = 5-m esityl-1,9-(2,4,6-Ph3C6H2)dipyrrin). Oxidation of the three-coordinate imido (L-Ar)Fe(NA...
