Abstract

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.

Keywords: Coumarins, nano-Fe3O4, malononitrile, azo aldehydes.
