Friedrichs F, Murphy B, Nayrat D, et al. An Improved Procedure for the Photoacylation of 1,4-Naphthoquinone with Aliphatic Aldehydes. SYNLETT. 2008;2008(20):3137-3140.Irradiation of 1,4-naphthoquinone at 300 25 rim 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
