| 摘 要： | 开展了邻苯二胺与4-甲基苯甲醛、4-硝基苯甲醛及4-二甲氨基苯甲醛反应生成苯并咪唑衍生物的微波辅助合成研究。用高效液相色谱法(HPLC)测定其产率。结果表明:相同反应时间,在微波辅助条件下,生成苯并咪唑衍生物的反应产率均较常规加热条件下增大,并且芳醛对位上取代基吸电子能力越强,反应产率越高。

| Abstract: | Microwave assisted organic synthesis of benzimidazole derivatives through the reaction of o-phenylenediamine with 4-nitrobenzylaldehyde,4-methylbenzylaldehyde and 4-dimethylaminobenzylaldehyde was investigated.High performance liquid chromatography(HPLC)was applied to the determination of the yield.The results showed that the yield was improved significantly when the reaction was carried out under microwave irradiation.When the electron withdrawing ability of substituent at p-benzaldehyde became stronger,the yield of the reaction was improved too. |
