Phosphomolybdovanadic acid catalyzed oxidation of 2,6-dimethylphenol into para-quinone in a biphasic system
In this paper, we disclose the results of our extended investigations on the reactivity of modified-type vanadium-containing heteropoly acids H a P z Mo y V x ′ O b (HPA-x′) towards the oxidation of 2,6-dimethylphenol (2,6-Me 2 P). This reaction is of great value as an effective way to the correspon...
