Abstract

Reaction of Ru3(CO)12and S(C≡CSiMe3)2in toluene gave [Ru3(CO)9(μ-η2-SC≡CSiMe3)(μ3-η2-C≡CSiMe3)] 1. The thermolysis of 1 provokes the rupture of the S-Cspbond of the SC≡CSiMe3ligand and C-C coupling reactions between two acetylide groups affording the clusters [Ru3(CO)9(μ3-S)(μ3-η2-C(SiMe3)C(C≡CSiMe3)] 2, [Ru2(CO)6-(μ-η3-SC≡CSiMe3)(μ-η2-C≡CSiMe3)]3, [Ru4(CO)12(μ4-S)(μ-η2-C≡CSiMe3)2] 4 and [Ru4(CO)9(μ-CO)2(μ4-S) (μ4-η2-C(SiMe3)C(C≡CSiMe3)] 5. All compounds have been characterized by IR and NMR techniques as well as FAB+mass spectrometry. Crystal structures of 1, 4, and 5 have been determined by X-ray diffraction methods. The pathways of the thermolysis of 1 to give 2-5 have been investigated.
