A solvent effect was found on the photoreactions of 1-aryl-3-tosyldihydro-1,3-diazaazulanones with a low pressure mercury lamp. Thus, ion pairs between p-toluenesulfonate anion and the corresponding 1-aryl-1,3-diazadihydroazulanone cations were afforded b

Low pressure mercury lamp irradiations of N-aryl-N'- tosyldihydrodiazaazulanones in acetonitrile afforded the corresponding N- aryldiazaazulanones. Analogous photoreactions but using tetrahydrofuran as a solvent gave ion pairs between p-toluenesulfonate (
