The photolysis of ethoxalyl azide gives ethoxalylnitrene and ethoxycarbonyl isocyanate. The nitrene adds to C=C double bonds and is inserted into O–H and C–H bonds. At high ethanol concentrations, where the singlet nitrene predominates, the O–H insertion product is formed dominantly. At low ethanol concentrations, where much of the nitrene changes to the triplet state, the hydrogen-abstraction product
乙二酰叠氮化物的光解得到乙二酰氮烯和乙氧羰基异氰酸酯。氮烯添加到 C=C 双键并插入 O-H 和 C-H 键。在高乙醇浓度下,单线态氮烯占主导地位,O-H 插入产物主要形成。在低乙醇浓度下,其中大部分氮烯变为三重态,优选脱氢产物。氮烯对 2-甲基丁烷的 C-H 键的反应性比乙氧羰基氮烯更具选择性。
