Acetyl-/>-benzoquinone derivatives are expected to show interesting chemical and biological properties, owing to the presence of an acetyl carbonyl group conjugated to quinone double bond. However, only acetyl-/?-benzoquinone has been reported in the literature13. An attempt was made as described below to synthesize several acetyl-p- benzoquinone derivatives, eg, 2-methyl-5-acetyl-p-benzoquinone (acetyltoluquinone), 2, ...
