Summary:The DFT approach is used to analyse the mechanism and controlling factors of (PDI)Fe II (N 2 ) 2 and (PDI)Fe II Cl(OEt 2 ) complexes ( i.e. a combination of a earth-abundant metal (Fe) and a non-innocent bis(imino)pyridine (PDI) ligand) catalyzed benzylic CH bond functionalization by unsubstituted and donoracceptor diazocarbenes. Results suggest that the use of (PDI)FeCl(OEt 2 ) complex and donoracceptor carbenes is absolutely necessary for the benzylic CH bond alkylation. Furthermore, the non-innocent PDI ligand acts as a one-electron oxidant upon formation of the reactive (PDI)Fe(Cl)CR 1 R 2 carbenoid. Can the bis(imino)pyridine iron, (PDI)FeL 1 L 2 , complexes catalyze CH bond functionalization?
