GAS-PHASE CHEMISTRY OF METAL-OXIDE ANIONS - THE REACTIONS OF DIOXOMANGANATE(III), MNO2- AND TRIOXOMANGANATE(V), MNO3- IONS WITH ALIPHATIC-ALCOHOLS

Results of gas-phase reactions of MnO2BAR and MnO3BAR ions with a series of aliphatic C1-C4 alcohols show that C2-C4 primary alcohols are oxidized by MnO2BAR in reaction channels which involve proton abstraction and hydride-ion transfer, along with the appearance of [H.Mn.O.OH]-ions. Secondary alcohols are oxidized in slower processes while methanol and t-butanol are unreactive. MnO3BAR/alcohol reactions are more complex and involve the formation of [H.MnO3]-, [H.Mn.O2.OH]-, [RO.Mn.O.OH]-, [(RO)2 Mn.O]- and the terminal solvated ion [(RO)3.Mn.OH]-.
