“…In several decades, the studies of Schiff bases have been made to synthesize Schiff bases and their complexes to apply these compounds in the different fields of study [1][2][3][4][5][6]. So, the metal complexes of Schiff bases have been attracted attention of bioinorganic researches due to their antimicrobial, antibacterial, antifungal, antiviral, anti-mycobacterial, anti-inflammatory, analgesic, anti-tubercular and antioxidant activities [7][8][9].…”

The synthesis, spectral, catalytic and antioxidant properties of ethyl-2-(2-hydroxy-3-methoxybenzylideneamino)-6-methyl-4,5,6-tetrahydrobenzo[b]thiophene-3-carboxylate (L) substituted iron(II), manganese(II), zinc(II), and ruthenium(II)-arene chlorides are described for the first time. The ligand and its metal complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, and spectral ( 1 H NMR, 13 C NMR, FT-IR, UV-Vis and Mass) techniques. The FT-IR spectra showed that the ligand can act as bidentate or tridentate. Magnetic moments and electronic spectral studies revealed an octahedral geometry for all the complexes obtained. The thermal behavior of the complexes showed that the water molecules were separated in the first step followed immediately by decomposition of the anions and ligand molecules in the subsequent steps. Ru(II) complex was used as catalysts for the transfer hydrogenation of ketones. At the same time, the effect of various bases such as NaOH, KOH, KOBu t and NaOAc as organic base were investigated in the transfer hydrogenation of ketones by 2-propanol as the hydrogen source.The complexes and ligand were tested in vitro for their antioxidant activity. The experimental results showed that Ru(II) complex had more potent antioxidant activities than Zn(II), Fe(II), Mn(II) complexes and parent ligand.

“…In several decades, fruitful efforts have been made to design and synthesize Schiff bases and their complexes to apply these compounds in the different fields of study [6][7][8][9]. A variety of transition metal complexes with bi-, tri-and tetradentate Schiff bases containing oxygen and nitrogen donor atoms are of particular interest, because of their ability to possess unusual configuration, and remarkable biomedical activities [10][11][12][13][14].…”
