TRICHLOROTRIAZINE AS A SIMPLE AND EFFICIENT CATALYST PROMOTER FOR THE SYNTHESIS OF NEW GENERATION OF COUMARINS
2013
Journal of the Chilean Chemical Society (Print)
Preserved Fulltext
The first synthesis of azo bearing coumarins from azo aldehydes and malononitrile in the presence of an efficient catalyst, trichlorotriazine under ultrasound irradiation 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 FTIR, NMR and elemental analysis.
