A series of ruthenium(II) p-cymene complexes containing Schiff-base ligands [Ru(p-cymene)LCl] [HL = pyridyl-salicylimine (2a-2d); HL = thiazol-salicylimine (2e-2h); HL = benzothiazol-salicylimine (2i-2l)] have been synthesized and characterized. All Schiff-base ligands and half-sandwich ruthenium complexes were fully characterized by 1H and 13C NMR spectra, mass spectrometry, and infrared spectrometry. The molecular structures of ruthenium complexes 2b and 2k were further confirmed by single-crystal X-ray diffraction methods. Furthermore, these half-sandwich ruthenium complexes are active catalysts for the mild hydrogenation of nitroarenes to aromatic anilines in the presence of sodium tetrahydroborate reducing agent in water. The most efficient catalyst, 2b, was found be compatible with nitroarenes of various functional groups.
Mixed ligand complexes with 4-aminoantipyrine derivatives to combat natural antioxidant system: Synthesis, characterization and biological studies

, p. 790 - 802 (2015/02/05)
Novel 4-aminoantipyrine based mixed ligand metal complexes with the Schiff bases of L1 (L1-4-aminoantipyrine with furfuraldehyde and L2/L3/L4/L5 are and L2-2-aminophenol with salicylaldehyde, L3-2-aminophenol with cinnamaldehyde, L4-2-aminobenzothiazole with salicylaldehyde, L5-2-aminobenzothiazole with cinnamaldehyde) were synthesized. The structures of the mixed ligand complexes were established by analytical and spectral techniques. They were screened for in vitro antimicrobial activity against of bacteria and fungi by disc diffusion method. The interaction of metal complexes with calf thymus-DNA (CT-DNA) was investigated by UV-visible, cyclic voltammetry, viscosity and thermal denaturation studies. DNA interaction studies suggest that metal complex binds to calf thymus-DNA through intercalation mode. Superoxide dismutase activity of these complexes has also been studied. The free ligands and their metal complexes have been tested for in vitro antioxidant activity by the reduction of 1,1-diphenyl-2-picryl hydrazyl (DPPH). The antioxidant activities of the complexes were studied and compared with the activity of ascorbic acid. Copper(II) complex showed superior antioxidant activity than other complexes.

Desai,Dalal
experimental part, p. 1625 - 1627 (2011/12/22)
[2-Imine-(1'-hydroxy)-phenyl]benzothiazole (III) was prepared and coupled with different diazotized substituted aniline derivatives (Va-l) and their dyeing performance on polyester fabric was assessed. All the compounds (VIa-l) shows good substantivity for polyester fabric and gave bright yellow to brown shades with good to excellent light, wash, rubbing and sublimation fastness.
