Polystyrene-supported ion pairs, generated from PtCl4 and Dowex® 1 anion exchangers in EtOH, were shown to be leach-proof and recyclable catalysts for hydrogenation of alkenes and for other unsaturated compounds at <35°C. In the hydrogenation of 1-decene the intraparticle diffusion of the substrate was found to contribute to the overall rate of the process. XPS analysis revealed the presence of Pt(II) and Pt(IV) species in the reaction mixture. No detectable amount of Pt(0) could be traced even after completion of the catalytic process.
