Whereas the dinuclear manganese(IV) complex [LMn(O)(3)MnL] (PF6)(2) ( 1a, L = 1,4,7-trimethyl-1,4,7-triazacyclononane) does not react with H2O2 in acetonitrile solution containing cyclohexane, acetic acid added to this mixture in small amounts induces the catalytic decomposition of hydrogen peroxide to O-2 and H2O ( catalase activity) and the transformation of cyclohexane to cyclohexyl hydroperoxide ( oxygenase activity). Addition to the acetic acid containing solution only 2 equivalents ( relative to the Mn catalyst) of a base enhances the catalase activity and suppresses the oxygenase activity. The proposed mechanism includes the formation of dinuclear dihydroperoxy derivatives of manganese, which can be transformed under the action of acetic acid to O = Mn( V) Mn( IV) OOH species. The latter can abstract a hydrogen atom from an alkane. The interaction of the so-formed R* radical with Mn(IV)-OOH can give the alkyl hydroperoxide, ROOH, which is the main primary product of the oxidation process.
