More Information
Summary:New six-coordinate ruthenium(III) Schiff-base complexes of general formula [Ru(X)(PPh 3 )(L)] (where X = Cl/Br and L = mononucleating bibasic tetradentate ligand derived by condensing actetoacetanilide/acetoacetotoludide with o-aminophenol/o-aminothiophenol/o-aminobenzoic acid in 1 : 2 molar ratio in ethanol) have been synthesized and characterized by physico-chemical and spectroscopic methods. The new ruthenium(III) complexes possess 2NO/2NS metal binding sites and are catalysts for the oxidation of alcohols using molecular oxygen as co-oxidant and in C-C coupling reactions. These complexes possess good biocidal (antibacterial and antifungal) activity.
