A variety of aryl iodides, bromides and activated aryl chlorides underwent the coupling with imidazoles, promoted by the catalyst 4, in moderate to good yields without the protection by an inert gas.展开更多

Various 1-aryl-1,2,3-triazoles were prepared in 63%-97% yields in water at 30℃ without any additives and avoiding the isolation of unstable aryl azides.展开更多
