Irradiation of styrene (5) in the presence of pyrimido[5,4-g]pteridine IO-oxide (1) with u.v.-visible light resulted in the formation of styrene oxide (6) and phenylacetaldehyde (7) which are proved as primary metabolites of (5). Chemical and physico-chemical facts showed that the photooxygenation o
