|Abstract: ||The oxidation of 2,6-di-tert-butylphenol with tert-butylhydroperoxide Bu O H has been studied using polymer XAD 24 anchored salicylaldoxime, 1,3-propylene-bis-salicylaldimine and o-phenylene-bis-salicylaldimine complexes of molybdenum
and vanadium in acetonitrile. The predominant products formed in the oxidation reactions were 2,6-di-tert-butylben-zoquinone BQ and 3,3 -5,5 -tetra-tert-butyldiphenoquinone dPQ , whereas with some only 2,6-di-tert-butylbenzoquinone
was formed. This is the first reported use of polymer anchored molybdenyl and vanadyl complexes in selective oxidation of
2,6-di-tert-butylphenol.Solvent plays an important role in this reaction. The effects of varying the ligand, metal and the
support on the catalytic activity in the oxidation of 2,6-di-tert-butylphenol have been studied. With polymer anchored.
MoO2 salpen , 81% of 2,6-di-tert-butylbenzoquinone was formed from 2,6-di-tert-butylphenol.|
