Abstract
Abstract Irradiation of 1, 4-naphthoquinone at 300±25 nm in benzene and in the presence of aliphatic aldehydes readily yields acylated hydroquinones in good to high yields. The developed protocol represents a significant improvement over the original procedure using medium-pressure mercury lamps. Subsequent oxidation gives the corresponding acylated quinones.
