An efficient and convenient method for the synthesis of aryl hydrazines has been developed via copper-catalyzed cross-coupling of aryl bromides and hydrazine with a readily accessible ligand and water as a solvent. The multigram scale procedure is applicable to aryl bromides bearing both moderately electron-donating and electron-withdrawing substituents in the aromatic nucleus. No column chromatography is required to obtain aryl hydrazine hydrochlorides in good yields.

A series of N2,N2′-disubstituted oxalic acid bishydrazides were synthesized. Some, for example, N2,N 2′-di-1-(4-methoxyphenyl)-ethanyloxylic-(bishydrazide), are novel and effective ligands for copper-catalyzed Ullmann-type Ci￡N coupling reaction in water. A variety of amines could be effectively N-arylated with aryl halides under both microwave irradiation and conventional heating (even at 30 °C) with good to excellent yields.
