Communication
NMR studies of 13C/12C isotopic patterns in Cu(III) intermediates and reaction products together with DFT calculations of possible reaction pathways indicate an intermolecular SN2 like substitution mechanism for ligand exchange reactions in square planar Cu(III) complexes, which is proposed to be slow compared to reductive elimination at synthetic conditions.
