Abstract: | 2-amino-5-( N-Carbazolyl methylene)-1,3,4-thiadiazole was compounded with carbazole、chloroacetic acid and thiosemicarbazide under nucleophilic substitution and closed-loop reaction.The compound 4-(9H-Carbazol-9-yl) benzaldehyde was prepared by carbazole with 4-chlorobenzaldehyde under refluxing by the catalysis of alkaline catalyst. At the same time, the new compound(4-carbazole-9-yl-benzomethylene)-(5-carbazole-9-methylene-1,3,4] thiadiazole-2-yl) amine was synthesized by 4-(9H-Carbazol-9-yl) benzaldehyde with 2-amino-5-(N-Carbazolyl methylene)-1,3,4-thiadiazole through solvent-free solid phase grinding method. The factors that influences on product yield were discussed by single factor method. The result that appropriate reaction conditions are as follows: molar ratio of reactants was 1∶1∶1.2, the reaction time was 20 minutes. The product was characterized by IR., 1H NMR UV-Vis and ele mental analysis. |
