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. In a Article，once mentioned of 32993-05-8, COA of Formula: C41H35ClP2Ru
The complexes [CpRuCl(PEt3)2 (1) and [CpRuCl(PMeiPr2)(PPh3)] (2) react with H2S in EtOH in the presence of NaBPh4 furnishing the green persulfide derivatives [{CpRu(L)}2-(mu-S2)][BPh4]2 (L = (PEt3)2, (PMeiPr2)(PPh3)), which were also obtained by reaction of 1 or 2 with elemental sulfur and NaBPh4 in MeOH. At variance with this, the reaction of [Cp*RuCl-(PEt3)2] (3) with H2S in EtOH afforded the RuIV hydrido-metallothiol [Cp*RuH(SH)(PEt3)2]-[BPh4], which has been structurally characterized, derived from the oxidative addition of SH2 to the electron-rich RuII moiety {[Cp*Ru(PEt3)2]+}. This compound is oxidized to yield the persulfide complex [{Cp*Ru(PEt3)2}2(mu-S 2)][BPh4]2, which was also obtained by reaction of 3 with elemental sulfur. The reaction of 1, 2, and 3 with 2-mercapto-pyridine (HSPy) in EtOH yielded cationic complexes in which HSPy is tautomerized to its 1H-pyridine-thione form as inferred from spectral data. Compound 1 reacts with potassium alkyl-xanthates KS2COR (R = Me, Et, iPr) yielding compounds of the type [CpRu(eta1-S2COR)(PEt3)2], whereas the reaction of 2 and 3 led respectively to the complexes [CpRu(eta2-S2COR)(PMeiPr2)] and [Cp*Ru(eta2-S2COR)(PEt3)], which contain one bidentate xanthate and one phosphine. The X-ray crystal structure of [Cp*Ru(S2COiPr)(PEt3)] was determined. In analogous fashion, the reaction of 1 with sodium diethyldithiocarbamate yielded [CpRu(eta1-S2CNEt2)(PEt3) 2], whereas 2 and 3 afforded the corresponding derivatives [CpRu(eta2-S2CNEt2)(PMeiPr 2)] and [Cp*Ru(eta2-S2CNEt2)(PEt3)].
