Novel vanadium-catalyzed oxidation of alcohols to aldehydes and ketones under atmospheric oxygen

[GRAPHICS] Oxidation of alcohols to aldehydes and ketones has been studied in high yields using atmospheric oxygen and a catalytic amount Of V2O5 in toluene under heating (ca. 100 degreesC). Secondary alcohols can be chemoselectively converted into ketones in the presence of primary hydroxy groups.
