Energetics of Proton-Coupled Electron Transfer in Hydroxy-Bridged Dicopper Complexes with N-Heterocyclic Carbene (NHC) Ligands.
A series of dinuclear μ-hydroxo bridged copper(II) complexes bearing N-heterocyclic carbene (NHC) ligands were designed to probe the ligand effect governing the activity patterns of particulate methane monooxygenase (pMMO). By systematically correlating experimental parameters (redox potentials E1/2 and acid dissociati...
