Cross-coupling reaction of aryl diazonium salts with azodicarboxylate using FeCl2†
Abstract
Arene diazonium salts have been employed as the aryl source in reaction with dialkyl azodicarboxylates to form N-aryl hydrazide derivatives. The optimum conditions are developed using FeCl2 in DMSO at 25 °C for 2 h. Various functional groups were tolerated under the optimum conditions.
