Electron-rich arenes react with bis(2,2,2-trichloroethyl) azodicarboxylate in 3 M lithium perchlorate-diethylether or acetone solution to produce para-substituted aryl hydrazides in high yields. The corresponding aromatic amines are readily obtained by reducing the hydrazides with zinc in acetic acid.
