Electron-rich arenes undergo electrophilic amination with diethyl azodicarboxylate on the surface of silica gel impregnated with indium trichloride in solvent-free conditions to afford para-substituted aryl hydrazides. Improved yields and enhanced rates are obtained by employing microwave irradiation.
