✦ Synopsis

A series of N 2 ,N 2 -disubstituted oxalic acid bishydrazides were synthesized. Some, for example, N 2 ,N 2 -di-1-(4-methoxyphenyl)ethanyloxylic-(bishydrazide), are novel and effective ligands for copper-catalyzed Ullmann-type C-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.
