Abstract: PP-I-45 Bulk and supported on γ-Al2O3 binary oxides RuIV-CoIII (Ru/Co = 1: 1-1:2) are chemoselective catalysts for liquid-phase oxidation of saturated and unsaturated primary and secondary alcohols to aldehydes and ketones with O2. The catalysts can be separated by filtration and reused. No leaching of Ru or Co in solution was observed. The alcohol oxidation appears to occur by a non-radical mechanism, which may be viewed as an oxidative dehydrogenation of alcohols to form an aldehyde or ketone. H2-TPR data suggest that the cobalt is likely to enhance catalyst reoxidation by O2 rather than to play a significant role in the alcohol dehydrogenation.
