Understanding the reactivity landscape for the activation of water until the formation of the O-O bond and O2 release in mol. chem. is a decisive step in guiding the elaboration of cost-effective catalysts for the oxygen-evolving reaction (OER). Copper(II) complexes have recently caught the attention of chemists as catalysts for the 4e-/4H+ water oxidation process. While a copper(IV) intermediate has been proposed as the reactive intermediate species, no spectroscopic signature has been reported so far. Copper(III) ligand radical species have also been formulated and supported by theor. studies. We found, herein, that the reactivity sequence for the water oxidation with a family of Copper(II) o-phenylene bis-oxamidate complexes is a function of the substitution pattern on the periphery of the aromatic ring. In-situ EPR, FTIR, and rR spectroelectrochem. studies helped to sequence the elementary electrochem. and chem. events leading toward the O2 formation selectively at the copper center. EPR and FTIR spectroelectrochem. suggests that ligand-centered oxidations are preferred over metal-centered oxidations rR spectroelectrochem. study revealed the accumulation of a bis-imine bound copper(II) superoxide species, as the reactive intermediate, under catalytic turnover, which provides the evidence for the O-O bond formation during OER. The experimental process involved the reaction of Ethyl oxalyl monochloride(cas: 4755-77-5Application of 4755-77-5)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Application of 4755-77-5
