Homogeneous oxidation of aromatic hydrocarbons using heteropolyvanadomolybdate-H_2O_2 catalytic system

摘要

Oxidation of alkylbenzenes in the liquid phase in the presence of heteropolyvanadomolybdate-hydrogen peroxide system leads to both side chain and ring hydroxylation. Selectivity pattern exhibited by this system resembles that of the vanadiumperoxo complexes, and differs from that of vanadium silicalite catalysed reactions indicating that the environment in which the active centre is present also plays a major role in the selectivity of the product pattern.
