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.

Unsaturated Carboxylic Acid

A simple and air-stable copper(I)/N-heterocyclic carbene complex enables the catalytic hydrogenation of hitherto unreactive enoates and enamides employing H2 as terminal reducing agent. This atom economic transformation replaces commonly employed hydrosilanes and can also be carried out in an asymmetric fashion.<br><br>
