The catalytical system, prepared from H2PtCl6 + SnCl2 · 2 H2O and the additives HBr and H2O in iso-butanol is very efficient for homogeneous hydrogenation of unsaturated esters under mild conditions. Reaction rates r up to 40 mMol · 1-1 · min-1 and turnover numbers UZ higher than 1.600 are observed.
