SYNTHESIS, CHARACTERIZATION AND STUDY OF BIOLOGICAL ACTIVITIES SOME NEW CHALCONE DERIVATIVES CONTAINING DIPHENYL AMINE MOIETY USING RECYCLABLE CATALYST SYSTEM.

In an effort to develop a series of substituted chalcone derivatives have been synthesized by claisen – Schmidt condensation. In the present study some new chalcones have been synthesized by the reaction of acetyl diphenyl amine with different aromatic aldehydes in the presence of aqueous solution of sodium hydroxides ethanol and PEG 400 used as a catalyst at room temperature. The structure of various synthesized compounds are assigned on the basis of elemental analysis, IR, NMR and Mass spectral data, the synthesized compounds were screened for antimicrobial activity.
