Whereas photoinduced, copper-catalyzed couplings of nitrogen nucleophiles with alkyl electrophiles have recently been shown to provide an attractive approach to achieving a variety of enantioselective C-N bond constructions, mechanistic studies of th

Here, we report the imidazolium-/pyrrolinium-substituted persistent zwitterionic ferrocenate derivatives, which were characterized by electron paramagnetic resonance (EPR) and 57Fe Mössbauer spectroscopy. Additional theoretical studies on these zwit

Here, we report the first isolable low-valent biscyclopentadienyl iron complexes stabilized by NHC-functionalized ligands (NHC-Cps), which were characterized by electron paramagnetic resonance (EPR) and 57Fe Mössbauer spectroscopy. Additional theore

The activity of nitrogenase enzymes, which catalyze the conversion of atmospheric dinitrogen to bioavailable ammonia, is most commonly assayed by the reduction of acetylene gas to ethylene. Despite the practical importance of acetylene as a substrate

The mechanisms of dioxygen activation and methane C-H oxidation in particulate methane monooxygenase (pMMO) are currently unknown. Recent studies support a binuclear copper site as the catalytic center. We report the low-temperature assembly of a hig

Here we report the formation of the first examples of dicopper(III) bis(μ-oxo) complexes ligated by the primary amines, propylenediamine, and N,N,-dimethyl propylenediamine. Stabilization of these new compounds is effected at -125 °C by "core captu

Structural mimicry of active sites is an attempt to inserta synthetic catalyst into an enzymatic mechanism. Sucha mechanism evolves by selection pressures for efficiency andtraverses an energetic path, with barriers and wells neithertoo high nor too

Histamine chelation of copper(I) by a terminal histidine residue in copper hydroxylating enzymes activates dioxygen to form unknown oxidants, generally assumed as copper(II) species. The direct formation of copper(III)-containing products from the ox
