The thermolysis of ethyl azidoformate in acetic and propionic anhydrides as solvent yielded the corresponding N-acyl-2-oxazolidinones (2a,b) in relatively significant yields.The other major products isolated were N-carboxyethyl-N,O-diacyl hydroxylamine (1a.b) and N,N,O-triacetyl hydroxylamine (3).The intramolecular cyclization is facilitated by the solvent.

Ethoxycarbonylnitrene (EtOCON) generated by α-elimination adds cleanly to allylic ethers giving substituted aziridines.Similar addition via nitrenium ion (EtOCONH+) gives derivatives of β-amino alcohols.
