| Abstract: | 2-Acetylthiophene(1) in yield 83.5% was prepared by the reaction of thiophene with acetic anhydride using phosphotungstic acid as the catalyst. Four new Schiff bases(2a～2d) in yields of 90%～95% were synthesized by the reaction of 1 with acylhydrazine. The structures were characterized by UV, ~1H NMR, ~(13)C NMR, IR and elemental analysis. The reaction condition of synthesizing 1 and 2 were optimized. |
