[Chemical Equation Presented] Carbonyldiimidazole (CDI) was found to mediate the Lossen rearrangement of various hydroxamic acids to isocyanates. This process is experimentally simple and mild, with imidazole and CO 2 being the sole stoichiometric byproduct. Significant for large-scale application, the method avoids the use of hazardous reagents and thus represents a green alternative to standard processing conditions for the Curtius and Hofmann rearrangements.

The corresponding esters and amides of aziridine-1,2-dicarboxylic acid were obtained by the reaction of esters and amides of aziridine-2-carboxylic acid with esters and amides of chlorocarbonic acid, isocyanates, and isothiocyanates.The reaction of 2-methoxycarbonylaziridine with diisocyanates and chlorides of the dicarboxylic acids leads to the formation of bisaziridines.
