The synthesis of azepine using ethoxycarbonyl nitrene involves the generation of a reactive nitrene intermediate from an appropriate precursor, typically an azidoformate such as ethyl azidoformate. Ethoxycarbonyl nitrene is a highly reactive species characterized by a divalent nitrogen atom with a lone pair and an empty orbital, making it electrophilic and capable of undergoing insertion reactions or cyclization. The reaction usually begins with the thermal or photochemical decomposition of ethyl
