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).
研究了 3-叠氮哒嗪,即四唑并 [1, 5-b] 哒嗪(I)的光解作用。未取代和甲基取代的化合物(Ia-d)生成了 3-氰基环丙烯(III)。另一方面,6-甲氧基化合物(Ie)产生了三烯(IV)和乙烯(V 和 VI)。这些化合物被认为是通过重氮中间体 (VIII) 和碳烯 (X) 形成的。
