Exclusive imidazole ligation to Cu III 2 O 2 and Cu III Cu II 2 O 2 cores

We disclose herein the synthesis and characterization of L2Cu(iii)2O2 and L3Cu(iii)Cu(ii)2O2 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 acc...

description We disclose herein the synthesis and characterization of L2Cu(iii)2O2 and L3Cu(iii)Cu(ii)2O2 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).
