Synthesis, structural characterization and catalytic transfer hydrogenation of ruthenium(II) carbonyl complexes bearing N,N,O pincer type benzoylhydrazone ligands

A simple route for the synthesis of four new Ru(II) carbonyl benzoylhydrazone complexes is described. The molecular structure was confirmed by a single crystal X-ray diffraction study. Further, the catalytic efficiency of the complexes has been evaluated for the transfer hydrogenation of substituted acetophenones to their corresponding secondary alcohols under optimized conditions.
