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.

<p>Two electron-reduction of the Ti(IV) guanidinate complex (Im<sup>Dipp</sup>N)(<sup>Xyket</sup>guan)TiCl<sub>2</sub> gives (η<sup>6</sup>-Im<sup>Dipp</sup>N)(<sup>xyket</sup>guan)Ti (1<sup>intra</sup>) and (Im<sup>Dipp</sup>N)(<sup>Xyket</sup>guan)Ti(η<sup>6</sup>-C<sub>6</sub>H<sub>6</sub>) (1<sup>inter</sup>) (<sup>xyket</sup>guan = [(<sup>t</sup>BuC=N)C(NXylyl)<sub>2</sub>]<sup>-</sup>, Xylyl = 2,5-dimethylphenyl) in the absence or presence of benzene, respectively. These complexes have been found to hydrogenate monocyclic and polycyclic arenes under relatively mild conditions (150 psi, 80 °C) – the first example of catalytic, homogeneous arene hydrogenation with TON > 1 by a Group IV system.</p>
