Abstract

The influence of ligands around peroxo niobium complexes and of the ratio of oxygen-source substrates towards the efficiency of the niobium(V)-catalysed oxidation of benzyl alcohol to benzaldehyde by hydrogen peroxide has been analysed: the use of ligands such as phenylphosphonic acid and 2,2′-bipyridyl associated with peroxoniobate gave efficient systems.
