Ethoxycarbonyl nitrene, generated by the photolysis of ethyl azidoformate (I), was inserted preferentially into the α C–H bonds of acyclic ethers. Each of the reactions with acyclic ethers gave N-alkoxyurethane via a cleavage of the C–O bond, indicating that an O–N ylide is an intermediate of the nitrene reaction. Comparing sensitized photolysis with direct photolysis of I in ethers and in alcohols, it was
由叠氮甲酸乙酯 (I) 光解产生的乙氧羰基氮烯优先插入无环醚的 α C-H 键中。与无环醚的每个反应都通过 C-O 键的断裂产生 N-烷氧基氨基甲酸酯,表明 O-N 叶立德是氮烯反应的中间体。将敏化光解与 I 在醚和醇中的直接光解进行比较,发现氮烯插入醚的 α C-H 键时发生单线态和三线态,插入 β 和 γ C-H 键醚和醇的 O-H 键仅对单线态进行。
