A series of new mononuclear Ru(III) complexes bearing phenoxy-imine Schiff base tetradentate ligands (phenylimino, 4-chlore phenylimino, 3,4-dichlore phenylimino) have been prepared and characterized by elemental analysis, TGA, UV-VIS, FT-IR, 1H-NMR and 13C NMR spectra. The proposed structure of the ligands have a O2N2 core to form mononuclear Ru (III) complexes. Preliminary studies on the catalytic performances of the compounds in the cycloalkane oxydation are described. The catalytic effect of all Ru complexes results in the epoxidation reaction of cyclohexane, as shown in the substrate conversion reaction appears to be very high.
