N2 - For the first time, it has been shown that chiral bipyrrolidine derived bioinspired non-heme iron complexes of the types [LFeX2], [LFe(μ-O)2FeL][X]4, and [LFe(μ-O)(μ-OAc)FeL][X]2 (where L – aminopyridine ligand, X− = OTf−, SbF6 −, ClO4 −) are capable of efficiently conducting aerobic oxidative coupling of 2-naphthols in an asymmetric fashion, with formation of the corresponding enantiomerically enriched BINOLs (up to 56% ee) in good yields (up to 94% within 24 h), using as little as 1 mol% of the catalyst. The effect of ligand substitutents, solvent, counteranion, 2-naphthol structure, and oxygen pressure on the catalytic performance has been systematically examined.
