The photo-excitation of anthracene (1) in the presence of benzoyl chloride and its p- or m-substituted compounds (2) gave the corresponding 2- and 9-aroylanthracenes. No isomeric 1-aroylanthracenes (3) were detected. The aroyl chlorides (2) were found to quench the fluorescence of 1. The quenching constants obtained increased with increasing electron-withdrawing ability of the substituents and are
