In the present study, a series of novel Schiff bases of isatin were synthesized by condensation of imesatin with different aromatic aldehydes. The imesatins were synthesized by reaction of isatin with p-phenylenediamine. The chemical structures of the synthesized compounds were confirmed by means of IR, 1H-NMR, mass spectroscopy, and elemental analysis. These compounds were screened for antioxidant activity by DPPH radical scavenging activity. In this method, the compound 3-(4-(4-dimethylaminobenzylideneamino) phenylimino) indoline-2-one (5c) showed highest antioxidant activity because of the presence of electron donating group.
