Iron(III) Chloride Catalyzed Formation of Aryl Hydrazides from Electron-Rich Arenes and Azodicarboxylates

Iron(III) chloride-catalyzed direct amination of electron-rich arenes with azodicarboxylates gives the corresponding aryl hydrazides in moderate to good yields within two minutes under mild conditions. This method will serve as an important tool for the synthesis of bioactive nitrogen-containing products and pharmaceuticals.
