dc.description.abstract	The AHA coupling of amines, haloalkane and alkynes under UV visible light was achieved with a higher yield in the presence of Au/Fe2O3. The catalyst was prepared by two methods using diferent gold content and then characterized by XRD, UV– vis, BET, TEM, ICP-OES and TPR spectroscopies. A comparative study of the ordi nary and photocatalytic conditions, showed that the UV visible light could activate the gold nanoparticles and lead to the formation of CH2Cl• and Cl• radicals through CH2Cl2 fragmentation. The propargylamine was aforded at low temperature and a short time using 2% Au/Fe2O3. The catalyst was stable for fve cycles with good photoactivity.	en_US
