A series of photoacylations of 1,4-naphthoquinone with various aldehydes and using Pyrex-filtered UVB light was conducted under continuous-flow conditions. Acetone served as a triplet photosensitizer and convenient solvent that kept all materials in solution and could be easily removed. The corresponding acylated 1,4-naphthohydroquinone photoproducts were obtained in acceptable to excellent yields of 30–90% with residence times of just 70 min. The photoacylation process was successfully coupled with in-line oxidation to obtain acylated 1,4-naphthoquinones.
