Photolysis of 3-azidopyridazine, i.e., tetrazolo [1, 5-b] pyridazine (I) was examined. Unsubstituted and methyl-substituted compounds (Ia-d) afforded 3-cyanocyclopropenes (III). On the other hand, 6-methoxy compound (Ie) gave the triene (IV) and the ethylene (V and VI). These compounds are considered to be formed via the diazo intermediates (VIII) and the carbenes (X).
