Abstarct: The reaction of 1,3-dihydro-2H-benzimidazole-2-thione and 2-methylthio-1H-benzimidazole with propargyl bromide, afforded, 2-methylthio-1-(prop-2-one-1-yl)-1H-1-benzamidazole and 1-(prop-2-yn-1-yl)-2-(prop-2-yn-1-yl thio)-1H-benzimidazole respectively. Then, the reaction of these compounds with different aromatic azides in the presence of catalytic amount Cu(OAc)2 and sodium ascorbate at 50 ° C temperature in magnetized Water, new derivatives of 1,2,3-triazole lixnked 2-thiobenzimidazole were prepared in good to high yields. The advantages of this reaction are high reaction yields, mild reaction conditions and short reaction times.
