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, Computed Properties of C41H35ClP2Ru
The first ruthenium-propargyl complexes CpL2RuCH2C<*>CPh (L = CO (1) and PPh3 (2)) were synthesized by reaction of – with PhC<*>CCH2Cl or PhC<*>CCH2OS(O)2C6H4Me-p and of Cp(PPh3)2RuCl with PhC<*>CCH2MgCl, respectively.In contrast, treatment of – with HC<*>CCH2Cl affords the ruthenium-eta1-allenyl complex Cp(CO)2RuCH=C=CH2 (3).Complex 1 is protonated by HBF4 * OEt2 to BF4 (4a), which isomerizes within 2 h in acetone solution at room temperature to BF4 (4b).Compound 4b reacts with Pt(PPh3)2(C2H4) to give the ruthenium-substituted platinum(II)-eta3-allyl complex <(eta3-CH2C(Ru(CO)2Cp)CHPh)Pt(PPh3)2>BF4 as the anti isomer quantitatively.Compound 1 undergoes facile <3 + 2> cycloaddition reactions with tetracyanoethylene (TCNE) and p-toluenesulfonyl isocyanate (TSI); the latter reaction in CH2Cl2 solution at 25 deg C proceeds slightly more rapidly (1.3 times) than the corresponding reaction of Cp(CO)2FeCH2C<*>CPh.With Co2(CO)8, 1 yields the trinuclear (CO)3Co(mu-eta2-PhC<*>CCH2Ru(CO)2Cp)Co(CO)3, which undergoes very slow cleavage of the Ru-CH2 bond with CF3CO2H, and replacement of CO (at Co) with PPh3.The foregoing reactions are compared and contrasted with the corresponding reactions of Cp(CO)2FeCH2<*>CPh.Where a comparison has been made, 2 was found to react faster than 1; however, its chemistry tends to be complicated by the lower stability of products and a facile PPh3-CO ligand exchange.With TSI and Co2(CO)8, the products are analogous of those of 1, but with Fe2(CO)9, Cp(CO)(PPh3)RuCH2C<*>CPh and Fe(CO)4PPh3 are obtained instead of heteronuclear metal complexes.
