Behaviour of 4- [3-oxo-13-diarylpropyl] -1-phenyl-3,5pyrazolidindiones towards some nucleophilic reagents

ABSTRACT

Substituted pyrazolidinedione have received considerable attention in recent years and their application as dyes for plastics, paper and varnishes have been reported. Pyrazolidinedione derivatives exhibiting analgesic antipyretic, antirheumatic and antiphlogistic activities also have been reported. This prompted us to synthesize new pyrazolidinedione derivatives through the nucleophilic addition of l-phenyl-3, 5-pyrazolidinedione to chalcone and study the behaviour of the adducts towards different reagents
