Résumé
The dinuclear arene ruthenium complexes [RuCl<sub>2</sub>{C<sub>6</sub>H<sub>5</sub>(CH<sub>2</sub>)<sub>3</sub>OCO-<i>p</i>-C<sub>6</sub>H<sub>4</sub>-OC<sub>8</sub>H<sub>17</sub>}]<sub>2</sub> (<b>1</b>) and [RuCl<sub>2</sub>{<i>p</i>-C<sub>6</sub>H<sub>4</sub>(CH<sub>2</sub>COOCH<sub>2</sub>CH<sub>3</sub>)<sub>2</sub>}]<sub>2</sub> (<b>2</b>) have been obtained by dehydrogenation of the corresponding cyclohexadiene derivative with ruthenium chloride hydrate. The single-crystal X-ray structure analysis of <b>2</b> shows the arene ligands to be involved in slipped-parallel π–π stacking interactions with neighbouring molecules, thus forming infinite chains along the b-axis. The dinuclear complexes <b>1</b> and <b>2</b> react with two equivalents of triphenylphosphine (PPh<sub>3</sub>) to give in excellent yield the corresponding mononuclear phosphine complexes [RuCl<sub>2</sub>{C<sub>6</sub>H<sub>5</sub>(CH<sub>2</sub>)<sub>3</sub>OCO-<i>p</i>-C<sub>6</sub>H<sub>4</sub>-OC<sub>8</sub>H<sub>17</sub>}(PPh<sub>3</sub>)] (<b>3</b>) and [RuCl<sub>2</sub>{<i>p</i>-C<sub>6</sub>H<sub>4</sub>(CH<sub>2</sub>COOCH<sub>2</sub>CH<sub>3</sub>)<sub>2</sub>}(PPh<sub>3</sub>)] (<b>4</b>), respectively. The single-crystal X-ray structure analysis of <b>4</b> reveals the formation of a dimer through two C–HCl interactions in the solid state.
