A Putative Monooxygenase Mimic Which Functions via Well-Disguised Free Radical Chemistry¹

Abstract

The hydroxylation of cycloalkanes at 25 °C by the syringe pump addition of tert -alkyl hydroperoxides (10 and 1 equiv based on catalyst) to deoxygenated acetonitrile containing cycloalkanes (0.64 M) and 0.61 mM of the catalyst, [Fe III 2 O(TPA) 2 (H 2 O) 2 ] 4+, is demonstrated to be a reaction which involves freely diffusing cycloalkyl radicals, i.e., free alkyl radicals.
