Exclusive imidazole ligation to Cu III2O2 and CuIIICu II2O2 cores

Abstract

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).
