The simplest alkoxycarbonylnitrene, CH₃OC(O)N, has been generated through laser (266 and 193 nm) photolysis of CH₃OC(O)N₃ and CH₃OC(O)NCO and subsequently characterized by IR (¹⁵N, D-labelling) and EPR (|D/hc| = 1.66 cm⁻¹ and |E/hc| = 0.020 cm⁻¹) spectroscopy in cryogenic matrices. Two conformers of the nitrene, with the CH₃ group being in syn or anti configuration to the CO bond, have been unambiguously identified. Further UV light irradiation (365 nm) of the nitrene results in isomerization to CH₃ONCO, completing the frequently explored mechanism for the Curtius-rearrangement of CH₃OC(O)N₃.
