Abstract

A new series of hexa‐coordinated stable Ru(III) Schiff base complexes of the type [RuX(EPh~3~)(L)] (where X = Cl/Br; E = P/As; L = tetradentate N~2~O~2~ donor Schiff ligands) have been synthesized and characterized by elemental analysis, magnetic susceptibility measurement, FT‐IR, UV–vis, ^13^C{^1^H}‐NMR, ESR spectra, electrochemical and powder X‐ray diffraction pattern studies. The selective oxidation of alcohols to their corresponding carbonyl compounds occurred in the presence of N‐methylmorpholin‐N‐oxide (NMO), H~2~O~2~ and O~2~ atmosphere at ambient temperature as co‐oxidants and CC coupling reactions. Further, these new Schiff base ligands and their Ru(III) complexes were also screened for their antibacterial activity against K. pneumoniae, Shigella sp., M. luteus, E. coli and S. typhi.
