Copper-catalyzed C–N bond formation using dialkyl azodicarboxylate as the amination reagent
摘要:
An efficient copper-catalyzed reaction for C-N bond formation using aryl halides, dialkyl azodicarboxylate, and a hydride source is reported. Using this procedure, aryl iodides reacted at ambient conditions, while aryl bromides required heating to 60 degrees C to accomplish the transformation. Various functional groups were tolerated under the optimum conditions. (C) 2015 Elsevier Ltd. All rights reserved.

The reaction of pyrroles with diisopropyl azodicarboxylate yields 2- and 2,5-substituted derivatives. 3- and 1,3-substituted indolizines and are formed by the same route. Cycl[3.2.2]azines have been obtained from and with dimethyl acetylenedicarboxylate.
