Photooxygenation of azines, i.e., adamantanone azine ( 1 ) and benzonorborn-7-one azine ( 4 ), afforded in addition to the corresponding ketones, lactones derived from a carbonyl oxide intermediate via an electron transfer pathway. On the other hand, 4-substituted-1, 2,4-triazoline-3,5-diones ( TAD ) react with azine 1 to give a 1,3-dipole, an azomethinimine intermediate as nitrogen analogue of a carbonyl
嗪,即金刚烷酮嗪(1)和苯并降冰片7-一嗪(4)的光氧合除提供相应的酮外,还提供了通过电子转移途径衍生自羰基氧化物中间体的内酯。另一方面,4-取代的1,2,4-三唑啉-3,5-二酮(TAD)与嗪1反应生成1,3-偶极子,一种偶氮甲亚胺中间体,为羰基氧化物的氮类似物,在用偶极亲和剂治疗中得到[2 + 3]-环加合物。讨论了机械含义。
