Abstract
A series of N2,N2′-disubstituted oxalic acid bishydrazides were synthesized. Some, for example, N2,N2′-di-1-(4-methoxyphenyl)-ethanyloxylic-(bishydrazide), are novel and effective ligands for copper-catalyzed Ullmann-type CN 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.
