Publikováno v: Journal of the American Chemical Society. 143(30)

Redox-inactive metal ions play vital roles in biological O2 activation and oxidation reactions of various substrates. Recently, we showed a distinct reactivity of a peroxocobalt(III) complex bearing a tetradentate macrocyclic ligand, [CoIII(TBDAP)(O2

Synthesis, characterization and reactivity of non-heme 1st row transition metal-superoxo intermediates

Autor: Hyeonju Noh, Jaeheung Cho

Publikováno v: Coordination Chemistry Reviews. 382:126-144

Metalloenzymes activate dioxygen to generate metal-oxygen adducts that perform a wide range of biological functions. Among the metal-dioxygen intermediates, highly reactive metal-superoxo species are implicated as key intermediates in the catalytic c

Oxidation of Naphthalene with a Manganese(IV) Bis(hydroxo) Complex in the Presence of Acid

Autor: Donghyun Jeong, Jaeheung Cho, Edward I. Solomon, Keith O. Hodgson, Hyeonju Noh, Britt Hedman, James J. Yan

Publikováno v: Angewandte Chemie. 130:7890-7894

Naphthalene oxidation with metal-oxygen intermediates is a difficult reaction in environmental and biological chemistry. Herein, we report that a MnIV bis(hydroxo) complex, which was fully characterized by various physicochemical methods, such as ESI

Distinct Reactivity of a Mononuclear Peroxocobalt(III) Species toward Activation of Nitriles

Autor: Donghyun Jeong, Jaeheung Cho, Joan Selverstone Valentine, Takehiro Ohta, Hyeonju Noh, Takashi Ogura

Publikováno v: Journal of the American Chemical Society. 139(32)

A mononuclear side-on peroxocobalt(III) complex with a tetradentate macrocyclic ligand, [CoIII(TBDAP)(O2)]+ (1), shows a novel and facile mode of dioxygenase-like reactivity with nitriles (R—C≡N; R = Me, Et, and Ph) to produce the corresponding m
