| Abstract: | The anodic oxidation of hexaethyl- (HEB), hexa-methyl- (HMB), pentamethyl- (PMB) and 1,2,4,5-tetramethyl-benzene (TMB) on Pt in CH2Cl2 and CF3COOH (TFA) is examined by cyclic voltammetry and esr spectroscopy. HEB, HMB and PMB are oxidized to the corresponding radical cations in TFA. The anodic oxidation of HMB and PMB in CH2Cl2 results in radical cations with one methyl group more than the starting material. The mechanism of the formation of these radical cations is discussed for HMB. |
