S. Fujibayashi et al., AN EFFICIENT AEROBIC OXIDATION OF VARIOUS ORGANIC-COMPOUNDS CATALYZEDBY MIXED ADDENDA HETEROPOLYOXOMETALATES CONTAINING MOLYBDENUM AND VANADIUM, Journal of molecular catalysis. A, Chemical, 110(2), 1996, pp. 105-117
Various organic compounds were oxidized by molecular oxygen in the pre
sence of a catalytic amount of mixed-addenda heteropolyoxometalates co
ntaining molybdenum and vanadium. The catalytic activity of the molybd
ovanadophosphate was found to be greatly enhanced by supporting on cha
rcoal. The supported catalyst has high catalytic activity for oxidativ
e dehydrogenation of benzylic and allylic alcohols to the correspondin
g aldehydes and ketones (46-92%), nevertheless, the non-supported cata
lyst was inactive for the same oxidations under these conditions. 2,3,
6-Trimethylphenol was selectively oxidized to trimethyl-p-benzoquinone
, which is a precursor of vitamin E, in the presence of a catalytic am
ount of molybdovanadophosphate. In addition, the aerobic oxidation of
amines, alkyl-substituted phenols, and alkanes were also examined.
