In this research, eight new compounds were created from the interaction of a number of aromatic and aliphatic compounds with propargyl bromide to prepare the alkynes after that; alkynes is reacted with the organic azide to form eight new compounds of 1,2,3-triazole by click reaction Using copper as a catalyst After that an antioxidant was done For prepared triazole , DPPH radical scavenging activity and It was the best result values 76.54+-1.9 for compound 9 Compared to the standard model ascorbic acid values 86.03+-4.02 at 200 mg/ml concentration .
