The first synthesis of azo bearing coumarins from azo aldehydes and malononitrile in the presence of efficient
recyclable catalyst, nano particle Fe3O4 under ultrasound irradiation and under grinding reaction in high yield and short
reaction time is reported. In the other study, the first electrophilic substitution under ultrasound irradiation for the synthesis
of azo bearing coumarins was developed. All of synthesized compounds were characterized by IR, NMR and elemental
analysis.
报道了在超声照射和研磨反应下,使用高效可回收催化剂纳米颗粒
Fe3O4,从偶氮醛和
丙二腈中首次合成含偶氮的
香豆素类化合物,具有高产率和短反应时间。在另一项研究中,开发了在超声照射下进行首次亲电取代反应,用于合成含偶氮的
香豆素类化合物。所有合成的化合物都通过IR、NMR和元素分析进行了表征。
