摘要：

The kinetics of oxygen atom transfer from several cationic oxo(salen)manganese(V) [salen = N,N'-ethylenebis(salicylidineaminato)] complexes to organic sulphides have been studied spectrophotometrically in acetonitrile at 25 degrees C. The reaction follows an overall second-order kinetics, first-order each in sulphide and oxomanganese(V) complex. Electronic-substrate and electronic-oxidant effect studies reveal that the single electron transfer from sulphide to the oxo complex is the rate-controlling step. The redox potentials of the couple Mn-V/Mn-IV have been estimated by applying Marcus theory to the experimentally observed rate constants.
