The oxidation of water (H2O) to dioxygen (O2) is important in natural photosynthesis. One of nature's strategies for managing such multi-electron transfer reactions is to employ redox-active metal-organic cofactor arrays. One prototype example is the copper tyrosinate active site found in galactose oxidase. In this work, we have implemented such a strategy to develop a bio-inspired nickel phenolate complex capable of catalyzing the oxidation of H2O to O2 electrochemically at neutral pH with a modest overpotential. Employment of the redox-active ligand turned out to be a useful strategy to avoid the formation of high-valent nickel intermediates while a reasonable turnover rate (0.15 s-1) is retained.

Diethylene glycol-functionalized imidazo[1,5-a]pyridin-3-ylidenes (DEG-ImPy) have been developed as bifunctional N-heterocyclic carbene ligands. The DEG-ImPy Cu(i) complexes efficiently catalyzed the direct C-H carboxylation of benzoxazole with CO2, showing higher isolated yields than those with the N,N′-(2,6-diisopropylphenyl)imidazolylidene Cu catalyst.

Coordination chemistry of a new pyridine imidazole-2-ylidene ligand (pyN∧C) system with sterically hindered substituents toward rhodium(I) metal ions has been investigated. The rhodium complex [(pyN∧C)RhCl(COD)] (COD = 1,5-cyclooctad
