Title
Photooxidation of camphorquinone in polystyrene matrix
Abstract

The photoreactivity of low molecular camphorquinone (CQ) doped in aerated polystyrene matrix was studied. Irradiation at λ > 380 nm led mainly to the insertion of one oxygen atom between the carbonyl groups of camphorquinone (CQ) and to the formation of camphoric anhydride (6). Minor products were cyclopentenecarboxylic acids (10a–c). Participation of the matrix on CQ photooxidation was negligible. The mechanism of photoconversion of CQ has been suggested.

► Identification of camphorquinone (CQ) photooxidation products in aerated polystyrene. ► Mechanism of photooxidation of CQ in polystyrene was suggested. ► Comparison of photooxidation of benzil and CQ. ► Described photooxidation mimics the fate of CQ used in restorative dental resins.
