Description

Treatment of Pt(O2) (PPh3), with hydrogen in benzene at 65°C gave a dark brown amorphous complex which exhibited a catalytic activity for hydrogenation of olefins. The complex was identified to be PtO (PPh3) by means of elemental analysis, molecular weight determination, IR, mass, and ESCA spectra. The hydrogenation of styrene was of first order to the hydrogen pressure and to the Pt concentration and of zero order to the styrene concentration. The activation energy is 53.5 kJ ⋅mol-11-Pentene has been found to undergo hydrogenation and isomerization with solvent effects: the hydrogenation rate decreases in the order THF>MeOH>MEK>toluene>CH3CN and the selectivity for hydrogenation is THF>MEK>MeOH>toluene>CH8CN. The addition of PPh3 inhibited the hydrogenation bu t increased the selectivity for hydrogenation. The complex has no selectivity for olefin formation in the hydrogenation of conjugated dienes and acetylenes.
