Iron-Oxygen Intermediates in Bio-Inspired Catalytic Systems for Olefin Epoxidation

摘要

In the last few years, a family of bio-inspired non-heme iron catalyst for olefin oxidation has emerged that mimics the action of some non-heme iron enzymes. Ferrous complexes [Fe~(II)(TPA) (CH_3CN)_2] (ClO_4)_2 (1) (TPA = tris(2-pyridylmethyl)amine) and [Fe~(II)(BPMEN)(CH_3CN)2](ClO_4)2 (2) (BPMEN = N,N'-dimethyl-N,N'-bis(2-pyridylmethyl)-l,2-diaminoethane) represent the most effective bio-inspired catalysts investigated thus far.
