Significance

Selective aerobic oxidation of alcohols was catalyzed by a monomeric ruthenium species bound to the surface of micro-size copper hydrogen phosphate (RuCHP). RuCHP was readily prepared by mixing an aqueous RuCl3 solution and micro-size copper hydrogen phosphate (CHP). Aerobic oxidation of benzyl alcohol was carried out with RuCHP at 80 °C to give benz­aldehyde in 99% yield. This catalyst was reused three times without loss of activity. Thus, the second and third reusing runs of the aerobic oxidation gave benzaldehyde in 98% and 97% yield, respectively.
