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.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

An intramolecular Diels-Alder (IMDA) reaction was observed at room temperature between an allyl group and a chloroanthracenyl group that were both bonded to the vinylidene ligand of the cationic ruthenium complex [Ru]=C=C(CH2CH=CH2)CH(CH2CH=CH 2)(C14H8Cl)+ (6; [Ru] = Cp(PPh 3)3Ru). The vinylidene ligand functions as a mediator to bring the allyl and the chloroanthracenyl groups in proximity for the reaction to take place. For the two allyl groups in 6, only the one at Cbeta underwent the reaction. In the analogous triethylphosphine complex 6 , more electron-donating triethylphosphine ligands lower the rate of the IMDA reaction. For this IMDA reaction in several vinylidene complexes, each with a nonchlorinated anthracenyl ligand, the rate of the reaction is accelerated by the presence of an unsaturated functional group at Cgamma of the vinylidene ligand, particularly by a terminal alkynyl substituent. The solid-state structures of two IMDA reaction products have been determined by single-crystal X-ray diffraction analysis.

Reactions of the group 4 metallocene alkyne complexes [Cp 2M(L)(btmsa)] (Cp = eta5-cyclopentadienyl = eta5-C5H5, btmsa = eta2-Me 3SiC2SiMe3; 1: M = Ti, L = none; 2: M = Zr, L = pyridine) and of the [(triphos)CoI] moiety [triphos = 1,1,1-tris(diphenylphosphanylmethyl)ethane] with the benzylsulfanyl-substituted acetylenes PhCH2S-C2-SCH2Ph (3) and PhCH 2S-C2-SFmoc (4) (Fmoc = fluorenylmethoxycarbonyl) have been investigated. Complex 1 reacted with 3 to give a mixture of a violet solid and [Cp2Ti(SCH2Ph)2] (5). Subsequently, the violet solid transformed in toluene at 70 C into the dinuclear complex [(Cp2Ti)2(mu-kappa2-kappa2- BnSC4SBn)] (6) displaying two [Cp2Ti] moieties bridged by a 1,4-bis(benzylsulfanyl)-1,3-butadiyne in the trans configuration. Complex 6 was further degraded in toluene at 100C to the tetranuclear cluster [CpTiS]4 (7). Similar reactivity was deduced indirectly for the reaction partners 1/4 and 2/3. For CoI, the side-on alkyne complexes [(triphos)Co(3)](PF6) (9-PF6) and [(triphos)Co(4)](PF 6) (10-PF6) were obtained. Reductive removal of the benzyl groups in 9-PF6 and subsequent coordination of the [Cp(PPh 3)RuII]+ moiety led to the dinuclear complex [(triphos)Co(mu-eta2-kappa2-C2S 2)RuCp(PPh3)] (13) displaying acetylene dithiolate (acdt2-) in a side-on carbon-sulfur chelate coordination mode. In contrast, the reaction of 10-PF6 with piperidine under very mild conditions resulted in the thio-alkyne complex [(triphos)Co(PhCH 2SC2S)] (11) bearing a terminal sulfur substituent at the coordinated alkyne. However, a subsequent rearrangement reaction led to the CoIII dithiolene complex [(triphos)Co{S2C 2(NC5H10)(CH2Ph)}](PF6) (14-PF6). The intricate rearrangement very likely involves a dinuclear Co species with a eta2-kappa2 coordination of the C2S2 moiety. Sulfur-substituted alkynes show contrasting behaviour in their reactions with TiII and Co I. Whereas the TiII centre in the titanocene eta2-alkyne complex effects a cleavage of the alkyne C sp-S bond concomitant with C-C coupling, CoI in the [Co(triphos)] eta2-alkyne complex leads to loss of the benzyl groups to give either a heterobimetallic Co/Ru acetylene dithiolate complex or a dithiolene complex.

The synthesis and coordination complexes of the new 1,2,3-triazole phosphinite Ph2POCH2CH2[1,2,3-N3C(Ph)C(H)] (2) are described. Compound 2 reacts with H2O2, S8, and Se8 to afford the chalcogenides Ph2P(=E)OCH2CH2[1,2,3-N3C(Ph)C(H)] [E = O (3), S (4), and Se (5)]. The reaction of 2 with [Ru(eta6-cymene)Cl2] yielded [Ru(eta6-cymene)Cl2(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})] (6), which produced [Ru(eta6-cymene)(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})]2[OTf]2 (7) on further treatment with silver triflate (AgOTf); in 7, 2 acts as a bidentate (P,N) ligand. The reaction of 2 with [CpRuCl(PPh3)2] (Cp = cyclopentadienyl) in 1:1 and 1:2 molar ratios afforded the mono- and disubstituted complexes [CpRuCl(PPh3)(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})] (8) and [CpRuCl(Ph2P-OCH2CH2{1,2,3-N3C(Ph)C(H)})2] (9), respectively. Complex 9 reacted with silver triflate to yield the cationic complex [CpRu(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})][OTf] (10), in which one of the phosphinite ligands shows P,N-chelation. The reactions of 2 with [M(COD)Cl2] (M = Pd, Pt; COD = 1,5-cyclooctadiene) in 2:1 ratios yielded cis-[MCl2(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})2] [M = Pd (11) and Pt (12)]. The similar reaction of 2 with [PdCl(eta3-C3H5)]2 in a 2:1 ratio afforded [PdCl(eta3-C3H5)(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})] (13). The reaction of 2 with [AuCl(SMe2)] in a 1:1 ratio yielded [Au(Cl)(Ph2POCH2CH2{1,2,3-N3C(Ph)C(H)})2] (14). The molecular structures of 6, 7, 9, 11, and 12 were determined by single-crystal X-ray studies.

Hexa- and nonanitrile ligands were synthesized by the known CpFe +-induced hexaallylation of hexamethylbenzene in [FeCp(n 6-C6Me6)] [PF6] and nonaallylation of mesitylene in [FeCp(n6-l,3,5-C6H3Me 3],[PF6], respectively, followed by Pt-catalyzed regioselective hydrosilylation of the iron-free polyolefins using (chloromethyl)dimethylsilane and sodium iodide catalyzed Williamson coupling with p-hydroxybenzonitrile. The hexanitrile star was coordinated to the piano-stool ruthenium complex [RuCp(PPh3)2Cl] by substitution of the six ruthenium-bound chlorides with nitriles using TIPF 6 to give the hexacationic hexaruthenium star complex, whereas the analogous metalation reaction partly failed, due to bulk constraint with the nonanitrile ligand. The strategy that involved lengthening of the tethers of the latter, however, successfully provided a nonacationic nonaruthenium complex.

The structures of compounds 4, 5, 10 and 12 were determined by X-ray crystallography. Cyclic voltammetry of the halide-bridged complexes revealed shifts in the redox potentials of the metals, as compared to mononuclear model compounds. The shifts are consistent with electron donation between the metals through the halide bridge. Ru/Au complexes 8-11, which are bridged only by the bidentate phosphine, exhibited minimal electronic effects between the metal centers. This limited interaction between the metal centers in 8-11 is corroborated by UV/vis spectroscopy.

Synthetic Route of 32993-05-8, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 32993-05-8, C41H35ClP2Ru. A document type is Article, introducing its new discovery.

The catalytic performance of a series of novel cationic ruthenium(II) complexes with cyclopentadienyl and bidentate phosphine ligands was explored to establish a catalyst structure-performance relationship and gain mechanistic insight in the selective O-allylation of a phenol with allyl alcohol. It appears that catalysts containing bidentate phosphine ligands having geminal dialkyl substituents at the central atom of a C3-bridging group of the phosphine ligand are highly selective for O-allylation; apparently the presence of the substituents efficiently blocks the competitive and thermodynamically more favorable pathway to C-allylation. It appears that the electronic and structural properties of the Ru(II) precursor complexes in the solid state do not differ significantly from those of complexes containing unsubstituted analogous ligands, while the resulting catalysts show a vastly different catalytic performance. The complex [RuCp(dppp)](OTs), with the unsubstituted ligand, after six hours yields 70% conversion of phenol with a selectivity for O-allylation of only 27%, whereas the complex [RuCp(dppdmp)](OTs), with the dimethyl-substituted ligand, after six hours gives 60 % conversion of phenol with 82% selectivity for O-allylation. The results suggest that the geminal dialkyl substitution at the central carbon of the C3 bridge of the ligand primarily leads to an increased kinetic stability of the bidentate chelate under reaction conditions, such as in the proposed intermediate [Ru(IV)(Cp)(diphosphine)(allyl)]2+ complexes. This implies that the high kinetic stability of the diphosphine chelate bound to Ru blocks the pathway to the thermodynamically favored C-allylation product. The results provide an interesting example in which the application of the geminal dialkyl substitution in the bridge of a bidentate ligand serves as a diagnostic tool to probe the nature of the selectivity-determining step in a catalytic pathway in homogeneous catalysis.
