Abstract

Pyridine and quinoline N-oxides catalyze hydrolysis of 2,3,5,6-tetrachloro-p-benzoquinone to 2,5-dichloro-3,6-dihydroxy-p-benzoquinone in dilute aqueous acetonitrile. Their catalytic activity is much higher than that of the corresponding azines. Quinoline N-oxides react with 2,3,5,6-tetrachloro-p-benzoquinone in a concentrated dioxane solution in the presence of water to give 2,5-dichloro-3,6-dihydroxy-p-benzoquinone salts.
