Abstract:We herein report the synthesis of conjugated chromophoric molecule possessing aza stilbenes and oxindole frameworks under catalyst-free condition by the reaction of 4-amino benzene sulfonic acid with isatin, 5-Bromo Isatin and 5-Iodo Isatin. All the newly synthesized compounds were well characterized by using different spectroscopic techniques like FT-IR spectroscopy, NMR spectroscopy. The developed method was found to be efficient, which have tolerated halogen functional groups. Furthermore the developed meth… Show more
