Abstract
A comparative analysis between metal-based aerobic catalysts shows that FluoRuGel, an hybrid fluorinated silica solgel glass doped with the ruthenium species TPAP (tetra-n-propylammonium perruthenate), is a competitive catalyst for the aerial oxidation of alcohols. In particular, the FluoRuGel/O2 system is well suited for carrying out convenient oxidative dehydrogenations in dense phase CO2 smoothly affording high yields of a variety of structurally different aldehydes and ketones of high purity. The potential rewards of this new technology are numerous and go beyond simple elimination of both organic solvents and stoichiometric oxidants employed in traditional alcohol oxidations.
