The preparations of some μ-peroxo binuclear cobalt(III) complexes of macrocyclic tetra-aza-ligands and studies of the oxygenation and deoxygenation reactions

Abstract

The preparations of μ-peroxo complexes of the type [(H 2O)LCoO 2CoL(H 2O)] 4+) where L = C- meso and C- racemic-5,12-dimethyl-1,4,8,11-tetraazacyclotetradecane, Me 2[14] dieneN 4 and Me 4[14]dieneN[in4 are described. The oxygeneration of the yellow low spin cobalt(II) complexes of the macrocycles is discussed. The deoxygeneration of the μ-peroxo complexes in acidic solution has been studied kinetically.
