Abstract
The kinetics of oxidation of a few 4-substituted diphenyl sulphides with si x oxo(salen)manganese(V) complexes has been studied in acetonitrile spectro photometrically at 25 degrees C. The reaction is second order overall, firs t order each in the complex and the substrate. Based on effect of substrate and oxidant on the rate, a single electron transfer mechanism has been pro posed. Correlation analyses and mathematical treatment of the rate constant s establish that mere is an inverse relationship between reactivity and sel ectivity in both the sulphide and complex series.
