A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

Preparation of ruthenium silanethiolato complexes and their reactions with sulfur dioxide; possible models for the activation of SO2 in the homogeneously catalyzed Claus reaction
CpRu(PPh3)2SSiiPr3 (6a) was prepared by reacting [CpRu(PPh3)2(acetone)]BF4 and NaSSiiPr3. Complex 6a is substitution-labile and readily gave the mixed-ligand derivatives CpRu(PPh3)(L)SSiiPr3, where L = CO (6b), PMe3 (6c), P(OMe)3 (6d), upon treatment with the corresponding ligands. CpRu(dppe)SSiiPr3 (6e) was obtained from complex 6a and dppe via the intermediate formation of CpRu(PPh3)(eta1-dppe)SSiiPr3. Treatment of complex 6a with one equivalent of SO2 gave primarily unstable CpRu(PPh3)(SO2)SSiiPr3 (6f). However, complexes 6b-e inserted one equivalent of SO2 solely at their S-SiiPr3 function to give the unstable O-silyl thiosulfito complexes CpRu(PPh3)(L)SS(O)OSiiPr3 (L = CO (8b), PMe3 (8c), P(OMe)3 (8d)) as well as CpRu(dppe)SS(O)OSiiPr3 (8e). The S-H bonds of CpRu(PPh3)2SH (7a) and CpRu(dppe)SH (7b) added to PhNSO to give CpRu(PPh3)2SS(O)NHPh (9a) and CpRu(dppe)SS(O)NHPh (9b), respectively. The crystal structure of complex 6a was determined. Crystallographic data for 6a: triclinic, P1, a = 10.642(6) A?, b = 11.068(8) A?, c = 21.994(10) A?, alpha = 79.27(5), beta= 89.22(5), gamma = 62.32(4), V = 2246(2) A?3, Z = 2.
