Three new Schiff base rhodium (III) complexes, derived from three ligands, L1, L2 and L3 have been prepared and characterized by IR, 1 HNMR, mass spectra and the elemental analysis. These complexes have shown efficient catalytic activity in the transfer hydrogenation of wide variety ketones to the corresponding alcohols in formic acid/triethylamine solution under mild reaction conditions. Depending on the ketone, the percentage of conversion for RhL1 have been found to be (51-92%) compared to
