The mechanism of L-arginine oxidation by quinquevalent vanadium in the presence of cationic surfactant in sulphuric acid media. A kinetic study

The oxidation is first order each in [substrate] and the [oxidant]. The rea ction follows an acid catalysed path, exhibiting second order dependence in [H+]. Bunnett's plot indicates that water acts as a nucleophile. Protonate d form of oxidant has been postulated as the reacting oxidizing species. Th e rate studied at four different temperatures enabled us to calculate activ ation parameters. A suitable mechanism has been proposed.
