Ig. Kolesnik et al., P-Mo-V heteropoly acids as catalysts for oxidation of 2,6-dialkylphenols to the corresponding 2,6-dialkyl-1,4-benzoquinones by molecular oxygen, REACT KIN C, 68(2), 1999, pp. 339-346
A new method is proposed for synthesis of 2,6-dialkyl-1,4-benzoquinones by
oxidation of 2,6-dimethyl and 2,6-di-tert-butylphenols with oxygen in a two
-phase "water-organic" system in the presence of P-Mo-V heteropoly acids.
