A SIMPLE, EXPEDITIOUS AND GREEN PROCESS FOR KNOEVENAGEL CONDENSATION OF PYRAZOLE ALDEHYDES Jayant P. Sonar, Suresh U. Shisodia, Sandeep D. Pardeshi, Shrikant A. Dokhe, Ashok M. Zine, Rajendra P. Pawar, Shivaji N. Thore. Abstract | | | | Knoevenagel condensation of pyrazole aldehydes with malononitrile is selectively carried out using ammonium carbonate as a mild, cheap, efficient and selective catalyst, in aqueous media at ambient temperature under sonication. This method is green and providing an expeditious way for Knoevenagel condensation of pyrazole aldehyde
Key words: Pyrazole aldehyde, malononitrile, Knoevenagel condensation, ammonium carbonate, aqueous medium.
