Several types of air-stable N,O-coordinate half-sandwich iridium complexes containing Schiff base ligands with the general formula [Cp*IrClL] were synthesized in good yields. These stable iridium complexes displayed a good catalytic efficiency in amide synthesis. A variety of amides with different substituents were obtained in a one-pot procedure with excellent yields and high selectivities through the amidation of aldehydes with NH2OHHCl and nitrile hydration under the catalysis of complexes 1-4. The excellent and diverse catalytic activity, mild conditions, broad substance scope, and environmentally friendly solvent make this system potentially applicable in industrial production. Half-sandwich iridium complexes 1-4 were characterized by NMR, elemental analysis, and IR techniques. Molecular structures of complexes 2 and 3 were confirmed by single-crystal X-ray analysis.

Four ruthenium(II) p-cymene complexes with naphthalene-based Schiff base ligands [Ru(p-cymene)LCl] (2a–2d) have been synthesized and characterized. The half-sandwich ruthenium complexes were characterized by 1H and 13C NMR spectra, elemental analyses, and infrared spectrometry. The molecular structures of 2a, 2b, and 2c were confirmed by single-crystal X-ray diffraction. Furthermore, these half-sandwich ruthenium complexes are highly active catalysts for the hydrogenation of nitroarenes to anilines using NaBH4 as the reducing agent in ethanol at room temperature.

The bidentate Schiff base ligands (HLn) have been synthesized by condensation of 2-hydroxy-l-naphthaldehyde with aniline and its p-substituted derivatives in ethanol. Ruthenium(III) complexes of the type [Ru(Ln)2(H2O)2]Cl have been synthesized by the reaction of RuCl3·nH2O with the Schiff base ligands (in a molar ratio 1:2) in ethanol. The ligands and their Ru(III) complexes have been characterized by elemental analysis, magnetic susceptibility, spectroscopic (FTIR, UV-vis, 1H NMR and X-ray diffraction) and thermal analysis techniques. All the ruthenium(III) complexes are found to be stable, paramagnetic, low spin and octahedrally coordinated by the ligands through the nitrogen atom of the azomethine (-CN-) group and the oxygen atom of the deprotonated phenolic group. The molecular and electronic structures of the investigated ligands (HLn) were also studied using quantum chemical calculations. The complexes (1, 3 and 5) exhibited a catalytic activity for the oxidation of benzoin to benzil with moderate to high yield in the presence of sodium periodate as co-oxidant. The antibacterial activities of the ligands (HLn) and their Ru(III) complexes towards Gram positive and Gram negative bacteria have been investigated.
