In the conversion of 1 to 2, a nonoxidative and a subsequent oxidative phase were distinguished.In the first phase the formation of the intermadiates 3,4 and 5 was established.In the second phase the formation of a dioxetane is postulated as the immediate precursor in the light giving step.The autoxidative chemiluminescence appeared to be a general feature of 8-substituted pteridines bearing a Me group at the 7-position.The chemiluminescence spectra and their quantum yields are determined.
