New Schiff bases derived by the condensation of methyl, chloro, and bromo substituted 2' hydroxy propiophenones with aliphatic and aromatic amines have been synthesized. The Schiff bases are yellow solids with sharp melting points. Schiff bases The spectral characterization of these newly synthesized Schiff base ligands has been done.These Schiff bases were characterized by IR spectroscopy, Nuclear magnetic resonance spectroscopy, UV spectroscopy, and Mass spectroscopy. IR spectra confirmed the presence of the phenolic OH group and azomethine group.

Three bidentate Schiff bases having nitrogen and sulphur donor sequences were prepared by condensing S-benzyldithiocarbazate (NH2NHCS2CH2C6H5) with heterocyclic aldehydes. The reaction of diphenyltin dichloride with Schiff bases leads to the formation of a new series of organotin(IV) complexes. An attempt has been made to prove their structures on the basis of elemental analyses, conductance measurements, molecular weights determinations, UV, infrared, and multinuclear magnetic resonance (H1,C13, andS119n) spectral studies.

Abstract:
Manganosalen complexes are coordination compounds that possess a chelating salen-type ligand, a class of bis-Schiff bases obtained by condensation of salicylaldehyde and a diamine. They may act as catalytic antioxidants mimicking both the structure and the reactivity of the native antioxidant enzymes active site. Thus, manganosalen complexes have been shown to exhibit superoxide dismutase, catalase, and glutathione peroxidase activities, and they could potentially facilitate the scavenging of excess reactive oxygen species (ROS), thereby restoring the redox balance in damaged cells and organs.
