✦ Synopsis

The photoaddition of oxygen to organic molecules is a well documented reaction (1,2a) but the title compounds do not appear to have been studied in this connection. Irradiation (3) of a benzene solution of the oxazinone (Ia) (4) in aerated solutions gave a product, m.p. 213-6' (ex-acetone) for which structure (II) is Rl Rz p-NO2CeH4 Ph p-N02 C&4
