Abstract

The Schiff bases were prepared with aromatic aldehyde and aromatic amine using cashew shell extract as a catalyst under microwave irradiation. This reaction is rapid, efficient, and solvent-free and involves the one-pot synthesis of Schiff bases under microwave irradiation. The synthesized Schiff bases were characterized by Fourier transform infrared (FTIR) spectroscopy, H nuclear magnetic resonance (NMR) spectroscopy, C NMR spectroscopy, and gas chromatography-mass spectrometry (GC-MS). The advantages of the preparation of Schiff bases under microwave irradiation are high yield, shorter reaction time, easy, elimination of side products, and quick product isolation. The synthesized Schiff base derivatives are well known for their biological activity like antibacterial and antifungal activity.

摘要

以腰果壳提取物为催化剂，在微波辐射下，用芳香醛和芳香胺制备席夫碱。该反应快速、高效且无溶剂，涉及在微波辐射下一锅合成席夫碱。通过傅里叶变换红外（FTIR）光谱、氢核磁共振（NMR）光谱、碳核磁共振光谱和气相色谱 - 质谱（GC - MS）对合成的席夫碱进行了表征。微波辐射下制备席夫碱的优点是产率高、反应时间短、操作简便、消除副产物以及产物分离快速。合成的席夫碱衍生物以其抗菌和抗真菌等生物活性而闻名。
