The Formation of Acetylcatechol in the Photochemical Reaction of o-Benzoquinones with Acetaldehyde

Article abstract of DOI:10.1246/bcsj.55.3657

The irradiation of several alkyl-substituted o-benzoquinones in the presence of acetaldehyde gave the corresponding acetylcatechol and catechol monoacetates via the attack of the acetyl radical on the ground-state quinone molecule.In the reaction of 3,5-di-t-butyl- and 3-t-butyl-5-methyl-o-benzoquinones, the dimer of alkyl-substituted cyclopentadienone, generated by the photodecarbonylation of the quinones, was also obtained.
