| Abstract: | The efficient conversion of electron-poor aryl triflates to the corresponding aromatic amines was accomplished by using ZnCl2 complexes of organic amines as nitrogen source with K2CO3 as the base in DMSO.The coupling reaction was performed in air and ligand-free without the sealed vessel.A possible mechanism,which was different with aromatic nucleophilic substitution(SNAr),was proposed.The amination products were confirmed by1H NMR,IR and MS techniques. |
