A modular flow reactor for performing Curtius rearrangements as a continuous flow process
Organic and Biomolecular Chemistry, 2008The use of a mesofluidic flow reactor is described for performing Curtius rearrangement reactions of carboxylic acids in the presence of diphenylphosphoryl azide and trapping of the intermediate isocyanates with various nucleophiles.

DMAP Catalyzed One-Pot Curtius Rearrangement Using 1,1-Dimethyl-2,2,2-trichloroethoxycarbonyl Azide.
Organic Letters, 2023We report our development of a controllable, base-free, one-pot Curtius rearrangement using 1,1-dimethyl-2,2,2-trichloroethoxycarbonyl azide (DMTN3) with 4-(dimethylamino)pyridine (DMAP) as a catalyst.

Synthesis of New Dialkyl 2,2′-[Carbonylbis(azanediyl)]dibenzoates via Curtius Rearrangement
Synthesis, 2021The 2-(alkylcarbonyl)benzoic acids obtained by esterification of phthalic anhydride are converted into azide derivatives: alkyl 2-[(azidocarbonyl)amino]benzoates and to ureas: dialkyl 2,2′-[carbonylbis(azanediyl)]dibenzoates.
