The fascinating magnetic and catalytic properties of coordinatively unsaturated 3d metal complexes are a manifestation of their electronic structures, in particular their nearly doubly or triply degenerate orbital ground levels....

In this report, we present a structurally and spectroscopically characterized diorganocopper system in three distinct oxidation states: [CuCu] (), [CuCu] (), and [CuCu] (). These states are stabilized by a...

Nitrene radical compounds are short-lived intermediates in a variety of nitrogen-involved transformations. They feature either a singlet or a triplet ground state, depending on the electronic properties of the substituents....

Why does binding of dioxygen (O) to metal centers, the initial step of O storage, transportation, and activation, almost inevitably induce metal-to-O single-electron transfer and generate superoxo (O˙) species, instead...

Nitrosobenzene (PhNO) and phenylhydroxylamine (PhNHOH) are of paramount importance because of their involvement as crucial intermediates in the biological metabolism and catalytic transformation of nitrobenzene (PhNO) to aniline (PhNH). However,...

We report two bridging-diazene diiron complexes [Cp*Fe(8-quinolinethiolate)](μ-NH) () and [Cp*Fe(1,2-CyPCHS)](μ-NH) (), synthesized by the reaction of hydrazine with the corresponding thiolate-based iron half-sandwich complex, [Cp*Fe(8-quinolinethiolate)] () and Cp*Fe(1,2-CyPCHS) (). Crystallographic...

Reaction of a rare and well-characterized Mn-superoxo species, Mn(BDPP)(O⋅) (1, HBDPP=2,6-bis((2-(S)-di(4-bromo)phenylhydroxylmethyl-1-pyrrolidinyl)methyl)pyridine), with 4-dimethylaminophenol at -80 °C proceeds via concerted proton electron transfer (CPET) to produce a Mn-hydroperoxo complex, Mn(BDPP)(OOH) (2),...

Heteronuclear Fe(μ-H)Zn hydride Cp*Fe(1,2-CyPCH)HZnEt () undergoes reversible intramolecular C-H reductive elimination through coupling of the cyclometalated phosphinoaryl ligand and the hydride, giving rise to a formal Fe(0)-Zn(II) species. Addition of...

Lead-based radicals in the oxidation state of +1 are elusive species and are highly challenging to isolate in the condensed phase. In this study, we present the synthesis and characterization...

Here, we combined magnetometry, multi-frequency electronic paramagnetic resonance, and wave function based ab initio calculations to investigate magnetic properties of two high spin Co(II) complexes Co(BDPP) (BDPP=2,6-bis((2-(S)-di(4-R)phenylhydroxylmethyl-1-pyrrolidi-nyl)methyl)pyridine, R=H for 8;...
