Abstract

Mackay had found that prolonged ultraviolet irradiation of solutions of 2,5-diphenyloxazole (PPO) (1) in toluene resulted in the formation of an insoluble crystalline product 2 which accumulated above the meniscus; the formation of 2 was dependent upon the presence of dissolved oxygen and water in the solutions. The Compound 2 was not a simple degradation product of PPO (1); elemental analysis was compatible with the empirical formula C22H17O5N and the thermal decomposition of 2 gave equal molar amounts of carbon monoxide, benzoic acid, and dibenzamide. The study described in this dissertation was initiated to establish the structure of 2 and to determine the mechanism by which it formed.
