Acetoxy- or benzoyloxy-substituents adjacent to the carbonyl groups of anthraquinone, 1,4-naphthoquinone, naphthacene-5,12-quinone, benzophenone, and methyl benzoate are selectively converted into hydroxy-groups by treatment with trifluoroacetic acid containing small amounts of water.In the absence of water a reversible acidolysis occurs.Water reacts with the acylating agent, thus preventing the reverse reaction.Evidence is presented that the hydrolyses are of the AAC1 type.
