A series of copper(I)-α-ketocarboxylate complexes have been prepared and shown to exhibit variable coordination modes of the α-ketocarboxylate ligand. Reaction with O2 induces decarboxylation of this ligand, and the derived copper-oxygen intermediate(s) has been intercepted, resulting in hydroxylation of an arene substituent on the supporting N-donor ligand. Theoretical calculations have provided intriguing mechanistic notions for the process, notably implicating hydroxylation pathways that involve novel [CuI-OOC(O)R] and [CuII-O-? ? CuIII=O2-]+ species.
