The Cu super(I)/Cu super(II) and Cu super(I)/Cu super(III) catalytic cycles have been subject to intense debate in the field of copper-catalyzed oxidative coupling reactions. A mechanistic study on the Cu super(I)/Cu super(II) redox process, by X-ray absorption (XAS) and electron paramagnetic resona...
