Schiff base contains the Azomethine group prepared by reaction of the carbonyl group and amine group. In this project, Schiff bases of sulphanilamide on the treatment of imidazole-2-carboxaldehyde and Dehydroacetic acid have been synthesized. Further, their Nickel complexes have been synthesized. They were characterized by IR, Mass, NMR, UV-Vis spectra and found to have square planar geometry. They were screened with few bacteria and found to have good antibacterial activity against gram-negative bacteria. Further, NiO nanoparticles were synthesized by thermal decomposition of the above synthesized Nickel Schiff base complexes and found to have 93-98 nm particle size.

in Wiley Online Library (wileyonlinelibrary.com).Polystyrene-supported sulfonic acid has been found to be an efficient catalyst for the one-pot, three-component synthesis of 2H-indazolo[2,1-b]phthalazinetriones in greener solvent glycerol. Use of greener solvent glycerol along with a polymer-supported, low toxic, and inexpensive catalyst renders the method eco-friendly. High yields, simple product isolation procedure, and fluorescent and electroluminescent natures of the products are the noteworthy aspects of this protocol.
