Dioxygen activation and catalytic aerobic oxidation by a mononuclear nonheme iron(II) complex.
We have used dioxygen, not artificial oxidants such as peracids, iodosylarenes, and hydroperoxides, in the generation of a mononuclear nonheme oxoiron(IV) complex, [Fe(IV)(TMC)(O)]2+ (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), from its corresponding Fe(II) complex, [Fe(TMC)(CF3SO3)2]. The formation of oxoiron(IV) species by activating dioxygen was markedly dependent on iron(...
متن کاملSpectroscopic Characterization and Reactivity Studies of a Mononuclear Nonheme Mn(III)–Hydroperoxo Complex
We report the first example of a mononuclear nonheme manganese(III)-hydroperoxo complex derived from protonation of an isolated manganese(III)-peroxo complex bearing an N-tetramethylated cyclam (TMC) ligand, [Mn(III)(TMC)(OOH)](2+). The Mn(III)-hydroperoxo intermediate is characterized with various spectroscopic methods as well as with density functional theory (DFT) calculations, showing the b...
متن کاملFormation, stability, and reactivity of a mononuclear nonheme oxoiron(IV) complex in aqueous solution.
A mononuclear nonheme oxoiron(IV) complex bearing a pentadentate N5 ligand was prepared in aqueous solution; the pH dependence of its stability and reactivities was reported along with the mechanistic details of sulfide oxidation by the oxoiron(IV) species.
متن کاملA mononuclear nonheme cobalt(iii)-hydroperoxide complex with an amphoteric reactivity in electrophilic and nucleophilic oxidative reactions.
A mononuclear nonheme cobalt(iii)-hydroperoxide complex bearing a tetramethylated cyclam ligand, [(12-TMC)Co(III)(OOH)](2+), was synthesized and characterized spectroscopically and computationally; the cobalt(iii)-hydroperoxide complex exhibited an amphoteric reactivity in electrophilic and nucleophilic oxidative reactions.
متن کاملMononuclear nonheme ferric-peroxo complex in aldehyde deformylation.
A mononuclear nonheme ferric-peroxo complex bearing a macrocyclic tetradentate N4 ligand, [(TMC)Fe(III)-O2]+, was prepared and used in mechanistic studies of aldehyde deformylation; a catalytic aldehyde deformylation by a nonheme iron(II) complex, [Fe(II)(TMC)]2+, and molecular oxygen is reported as well.
