title: Identification of catalyst surface species during asymmetric platinum-catalysed hydrogenation in a "supercritical" solvent.
abstract: In situ attenuated total reflection infrared spectroscopy studies during the enantioselective hydrogenation of ethyl pyruvate in "supercritical" ethane over a chirally modified Pt/Al(2)O(3) catalyst show the preferential adsorption of ethyl pyruvate as cis-conformer and indicate a hydrogen bond interaction of this species with the co-adsorbed modifier cinchonidine.
