A novel Schiff base derived from curcumin and arginine was synthesized, reacting with Co, Ni, Cu, and Zn metal ions in order to build the stable complexes that were structurally confirmed by spectral methods i. e. The complexes' electronic and magnetic results indicate a tetrahedral pattern around the central metal ion except for the copper complex, which has square planar geometry. B. subtilis, B. thuringiensis, B. cereus, B. cereus, B. sphaericus, B. laterosporus species was tested for gram-positive bacteria using Schiff base and its metal chelates. Metal chelates had more antimicrobial activity than their parent cur-arg Schiff base, according to the study. The antioxidant activities of Schiff base and its complexes were also investigated, and the findings reveal increased activity for the metal complex.

The numerous review studies have shown that microwave technology is a versatile instrument for both synthesis and leading applications of Schiff base compounds. Using multiple examples from the new literature, this review establishes the empirical comparison between microwave and other synthetic methods for Schiff base ligands and their metal complexes in terms of kinetic parameters. These discussions will help the reader make a connection between the theoretical theory and the actual events involved in the creation of Schiff bases using microwave technology.

Novel Schiff base complexes with Co, Ni, Zn, and Cu metals were prepared and characterized by analytical, conductivity, thermon-NMR, UV–Visible, ESR, and fluorescence spectroscopy, magnetic moment, as well as cycle voltammetry, as well as cyclic voltammetry, respectively. Thermal stability and degradation kinetics have been investigated using thermogravimetric methods, and other thermal parameters have also been reported. Schiff base and its metal chelates were tested against a variety of bacterial species including P. aeruginosa, S. aureus, B. subtilis, E. coli, and A. flavus, according to A. n. . . . and A. flavus.
