Résumé
The reaction of [(arene)RuCl<sub>2</sub>]<sub>2</sub> (arene=C<sub>6</sub>H<sub>6</sub>, <i>p</i>-Me—C<sub>6</sub>H<sub>4</sub>—<i><sup>i</sup></i>Pr, C<sub>6</sub>Me<sub>6</sub>) with <i>p</i>-thiocresol, 2-mercaptoethanol and <i>p</i>-mercaptophenol in refluxing ethanol gives the tris-thiolato complexes [(arene) <sub>2</sub>Ru<sub>2</sub>(SR)<sub>3</sub>]<sup>+</sup> (R=<i>p</i>-C<sub>6</sub>H<sub>4</sub>—Me, CH<sub>2</sub>CH<sub>2</sub>OH, p-C<sub>6</sub>H<sub>4</sub>OH) which can be isolated as the chloride salts. The remarkable selectivity of (arene)ruthenium units for SH versus OH functions reflects the affinity of ruthenium towards sulfur.
