Abstract The reaction of (μ3-S)RuCo2(CO)9 (1) with [NaM(CO)3CpC(O)]2C6H4 [(M = Mo (2), M = W (3)] in refluxing THF gave two new carbonyl clusters, [(μ3-S)RuCoM(CO)8CpC(O)]2C6H6 [M = Mo (4), M = W (5)]. The structure of cluster 5 was established by X-ray diffraction analysis.

The synthesis, characterization, and thiophene hydrodesulfurization (HDS) activities of novel organometallic sulfide cluster catalysts are presented. The catalysts are composed of H2SRu3(CO)9, HSRu2Co(CO)9, SRuCo2(CO)9, and [(Co3S2(CO)7]2 supported on carbon and gamma-Al2O3. Although the clusters decompose at industrial HDS temperatures, the catalytic properties of the cluster catalysts at lower temperatures depend on the ratio of ruthenium and cobalt. Temperature-programmed decomposition (TPD) of the supported clusters in flowing hydrogen was monitored using FT-IR and mass spectrometry (MS). Temperatures of decomposition (as determined by the maximum rate of CO evolution) follow the order H2SRu3(CO)9 > HSRu2Co(CO)9 > SRuCo2(CO)9 > [Co3S2(CO)7]2. Significant amounts of H2O are detected as products of cluster decomposition on alumina. TPD/MS data of H2SRu3(CO)9 labeled with (CO)-O-18 indicate that the H2O evolved is mostly formed from the alumina surface and not from cluster-bound carbonyls.Kinetics measurements at 150-degrees-C show that the mixed-metal cluster catalysts are more active for thiophene desulfurization than catalysts containing only one metal component. This trend is reversed at higher temperatures and for catalysts sulfided at 400-degrees-C; that is, the mixed-metal catalysts are less active for thiophene desulfurization than catalysts containing only one metal component. The carbon-supported cluster catalysts are more active for thiophene hydrodesulfurization and more selective for butane formation than catalysts supported on gamma-Al2O3.
