| Abstract: | Double oxidation of CoIII(3,5-DTBCat)(3,5-DTBSQ)(bpy)] (1,ls-Co(III)) by AgBF4 and of CoII(3,5-DTBSQ)2(bpy)] (1,hs-Co(II)) by a mixture of HClO4/H2O2 yielded CoIII(3,5-DTBSQ) (bpy)2]X2, where X−=BF4− (4) and ClO4− (5), respectively. The mechanism for the double-oxidation process that leads to a loss of one of the quinone ligands and in some cases to a redistribution of the electronic charge is discussed here. |
