Enhanced selectivity in non-heme iron catalysed oxidation of alkanes with peracids: evidence for involvement of Fe(iv)O species

Abstract

Catalytic alkane oxidation with high selectivity using peracids and an (N4Py)Fe complex is presented and the role of [(N4Py)Fe(IV)=O]2+ species, molecular oxygen and hydroxyl radicals in the catalysis is discussed.

Synthesis, Structure and Spectral, and Electrochemical Properties of New Mononuclear Ruthenium(III) Complexes of Tris[(benzimidazol‐2‐yl)methyl]amine: Role of Steric Hindrance in Tuning the Catalytic Oxidation Activity

“…When treated with hydrogen peroxide 1 and 2 fail to generate the hydroperoxido intermediate as seen from a UV/Vis spectral study and no catalytic oxidation of alkanes is observed, which can be attributed to the formation of an inactive catalyst. [45] …”

Applications of Transition‐Metal Catalysts to Textile and Wood‐Pulp Bleaching

“…‐transfer is rate limiting. The {Fe IV O} species is assumed to be the only active species when hydrogen peroxide is replaced by peracids in the catalytic oxidation of cyclohexane 111a. The reaction is efficient under anaerobic conditions giving an increased alcohol/ketone reaction.…”

A Hexanuclear Iron(III) Carboxylate with an [Fe6(μ3‐O)3(μ2‐OH)]11+ Core as an Efficient Catalyst for Cycloalkane Oxidation

“…The development of synthetic, biomimetic model compounds12 for non‐heme iron proteins, such as methane monooxygenase (MMO), has opened up a new approach in alkane activation chemistry 1c,e,g. 13, 14b,c,d Some of these compounds were shown to be valuable model precursors for high‐valent μ‐oxo diiron species 12b,d. 14 Iron acetate, pivalinate, and picolinate species present in alkane activating systems of the Gif III and Gif IV and GoAgg III types have been extensively characterized 15.…”
