Vanadium (V) only possesses oxidising properties in acid solutions. The main species present in these conditions is that cation VO2+, but this is protonated to a small extent to give the more powerfully oxidising species V(OH)23+. Previous work in this laboratory has shown that vanadium (V) is a one-electron oxidising agent and is reduced by organic compounds to vanadium (IV) only. No vanadium (III) has yet been detected in any of these oxidation reactions while the presence of free radicals, which are usually associated with one-electron oxidations, has been demonstrated in many vanadium (V) oxidations of organic compounds. To extend the knowledge of these oxidations a number of alcohols, α-hydroxy acids, acyloins and aldehydes, and also pinacol and oxalic acid have been oxidised by acid solutions of vanadium (V). The products of these oxidations have been investigated and in many cases a detailed investigation of the kinetics of the reactions has been made.
