Exclusive Imidazole Ligation To Cuiii2o(2) And Cu(Iii)Cuii2o(2) Cores

We disclose herein the synthesis and characterization of L2Cu(iii)(2)O-2 and L3Cu(iii)Cu(ii)(2)O-2 complexes with nitrogen ligation exclusively from imidazoles for the first time. Their accessibility by direct oxygenation of a L-Cu(i) precursor and the resulting Cu(iii) formation inform on the kinetic accessibility and thermodynamic superiority of imidazole in stabilizing Cu(iii).
