Evidence for a manganese(III) intermediate, previously implicated in the [MnO4]--SO2 electron-transfer process, has been obtained by conducting the reaction in the presence of F-. A combination of in situ EPR and electronic absorption spectroscopies was used to follow the reaction course and physico-chemical techniques were used to ascertain the identity of the isolated manganese(III) products. The evidence suggests that in the presence of F- manganese(VII) is directly reduced to manganese(III) and thence to manganese(II).
