Résumé
The cationic complexes [HRu<sub>2</sub>(η<sub>6</sub>-arene)<sub>2</sub>{μ<sub>2</sub>-(<i>p</i>-X-C<sub>6</sub>H<sub>4</sub>)-S}<sub>2</sub>]<sup>+</sup> and [H<sub>2</sub>Ru<sub>2</sub>(η<sub>6</sub>-arene)<sub>2</sub>{μ<sub>2</sub>-(<i>p</i>-X-C<sub>6</sub>H<sub>4</sub>)-S}]<sup>+</sup> (arene = 1,2,4,5-Me<sub>4</sub>C<sub>6</sub>H<sub>2</sub> or C<sub>6</sub>Me<sub>6</sub>; X = Br and Me) are accessible in good yields from <i>p</i>-X-C<sub>6</sub>H<sub>4</sub>-SH with [H<sub>3</sub>Ru<sub>2</sub>(1,2,4,5-Me<sub>4</sub>C<sub>6</sub>H<sub>2</sub>)<sub>2</sub>][BF<sub>4</sub>] and [H<sub>3</sub>Ru<sub>2</sub>(C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>][BF<sub>4</sub>], respectively. The dibromo derivative [HRu<sub>2</sub>(C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>(<i>p</i>-Br-C<sub>6</sub>H<sub>4</sub>-S)<sub>2</sub>]<sup>+</sup> is found to undergo double Suzuki coupling reactions with 3-thiophene boronic acid to give [HRu<sub>2</sub>(C<sub>6</sub>Me<sub>6</sub>)<sub>2</sub>(<i>p</i>-C<sub>4</sub>H<sub>3</sub>S-C<sub>6</sub>H<sub>4</sub>-S)<sub>2</sub>]<sup>+</sup>. This dibromo complex is a potential precursor for the insertion of dinuclear hydrido organometallic entities in the main chain of conjugated molecules.
