1,1?-Bis(diphenylphosphino)ferrocene (dppf) reacted with RuCl(Ph3P)2Cp* to give RuCl(dppf)Cp* in good yield. The complex reacted with AgBF4 in acetonitrile to give [Ru(CH3CN) (dppf)Cp*]BF4 quantitatively and in acetone to give [Ru(eta2-O2) (dppf)Cp*]BF4 in good yield. The structure of the latter was determined by X-ray analysis. (±)-BINAP and (±)-DIOP were reacted with [RuCl2Cp*]n/Zn to give RuCl[(±)-BINAP]Cp* and RuCl[(±)-DIOP]Cp*, respectively, in moderate yields. They reacted with phenylacetylene in the presence of NH4PF6 to afford the corresponding RuII phenylacetylide complexes. The asymmetric condensation of phenylacetylene with allyl alcohol in the presence of these diphosphine complexes was unsuccessful.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II), name: Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II).

An unprecedented ruthenium-catalyzed direct and selective alkyne hydrochlorination is reported and leads to vinylchlorides in excellent yields with atom economy. The reaction proceeds at room temperature from terminal alkynes and provides a variety of chloroalkenes. Only the regioisomer resulting from the formal Markovnikov addition is selectively formed. Mechanistic studies show the stereoselective syn addition of HCl to alkynes at room temperature and suggest a chloro hydrido RuIV species as a key intermediate of the reaction.

Application of 92361-49-4. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.

A synthesis of neutral vinylideneruthenium complexes [RuCl(C=CHR)(PPh3)(eta-C5Me5)] (R = Ph, But or SiMe3) from [RuCl(PPh3)2(eta-C5Me5)] and 1-alkynes has been developed. This takes advantage of the presence of two bulky ligands (PPh3 and C5Me5), which results in displacement of one PPh3 ligand (rather than chloride) and concomitant isomerisation of the 1-alkyne to vinylidene ligands. The vinylidene complexes undergo facile loss of HCl on treatment with NaOMe in the presence of a 2e donor ligand (L) to give the neutral acetyhde complexes [Ru(C?CR)L(PPh3)(eta-C5Me5)] [R = Ph, L = PPh3, CO, O2 or dppm-P; R = But, L = PPh3, CO, C2H4, dppe-P, C2(PPh2)2-P, S2, P(OMe)3 or AsPh3]; the complexes [Ru(C?CBut)(L2)(eta-C5Me5)] [L2 = dppm or PPh2CH= CHPPh2] and [Ru(S2CC?CBut)(PPh3)(eta-C 5Me5)] were also obtained. Crystal structure determinations were carried out on eleven of the complexes.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II), molecular formula is C46H45ClP2Ru.

Micellar media in water provide a simple and efficient environment to favor the double bond isomerization of terminal alkenes catalyzed by the cationic half-sandwich complex 1 at 95 C. The micellar medium favors both catalyst dissolution in water by means of ion-pairing with the preferred anionic surfactants as well as substrate dissolution thus favoring its conversion into products.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C46H45ClP2Ru, you can also check out more blogs about92361-49-4

1-Ethynyl-2,3,4,5-tetramethylruthenocene was prepared by the reaction of 1-formyl-2,3,4,5-tetramethylruthenocene with trimethylsilyldiazomethyllithium and also by the reaction of 1-(2?,2?-dichlorovinyl)-2,3,4,5-tetramethylruthenocene, which was obtained from the reaction of 1-formyl-2,3,4,5-tetramethylruthenocene with lithium dichloromethyldiethylphosphonate and tert-butyluthium in good yield. 1-Ethynyl-2,3,4,5-tetramethylruthenocene reacted with RuClP2L (P2 = 2 PPh3 or dppe; L = eta-C6H6, eta-C5Me6, or eta5-C9H7) in the presence Of NH4PF6 or AgBF4, followed by the column chromatography on deactivated Al2O3, to give Ru(C? CRc?)P2L in moderate or good yield. Ru(C?CRc)P2(eta5-C9H7) and Ru(C?CRc*)P2(eta5-C9H 7) were similarly prepared (Rc, Rc?, and Rc* are ruthenocenyl, 2,3,4,5-tetramethylruthenocenyl, and l?,2?,3?,4?,5?-pentamethyhruthenocenyl, respectively). The structures of Ru(C?CRc?)(dppe)-(PPh3)2(eta-C 5H5), Ru(C=CRc)(dppe)(eta5-C9H7), and Ru(C?CRc?)(dppe)(eta5-C9H7) were determined by X-ray analysis. Cyclic voltammetry of the acetylide complexes showed two well-separated quasi-reversible waves. Chemical oxidation of ruthenium(II) 2,3,4,5-tetramethylruthenocenylacetylide complexes gave products whose stability was dependent on the ligand on the Ru(II) moiety. The 13C NMR spectrum of the oxidized species isolated as stable crystals confirmed the structural rearrangement of the bridging acetylide ligand to a imu-eta-eta6:eta 1-[(cyclopentadienylidene)ethylidene] ligand. The structure of [(eta-C5H5)Ru(eta-eta6:eta 1-C5Me4=C=C)Ru-(dppe)(eta5-C 5Me5)](BF4)2 was determined by X-ray analysis.

The hydrides RuH2(C5H6)(Pcy3)2 (2) and RuH(C5H5)(Pcy3)2 (3) (cy = cyclohexyl) are formed in the reaction of RuH6(Pcy3)2 (1) with cyclopentene, although in the presence of 3,3-dimethylbut-1-ene only (3) is formed quantitatively, but treatment of (1) with C5Me5H gives no C5Me5 complex (although in C6D6 active H-D exchange with the phosphine protons is observed); however n when treated with phosphine (L = PMe3, PPh3, P(i-Pr)3, or Pcy3) gives the paramagnetic complexes RuCl2(C5Me5)L, which on treatment with LiBHEt3 in tetrahydrofuran yields the new trihydrides RuH3(C5Me5)L.

The reaction of 2-guanidinobenzimidazole (GBI) and (eta5-C5H5)Ru(PPh3)2(Cl) in refluxing toluene gives the chelate [(eta5-C5H5)Ru(PPh3)(GBI)]+Cl- (1+Cl-; 96%). Subsequent anion metatheses yield the BF4-, PF6-, and BArf- (B(3,5-C6H3(CF3)2)4-) salts (77-85%). Reactions with CO give the carbonyl complexes [(eta5-C5H5)Ru(CO)(GBI)]+X- (2+X-; X- = Cl-, BF4-, PF6-, BArf-; 87-92%). The last three salts can also be obtained by anion metatheses of 2+Cl- (77-87%), as can one with the chiral enantiopure anion P(o-C6Cl4O2)3- ((delta)-TRISPHAT-; 81%). The reaction of [(eta5-C5H5)Ru(CO)(NCCH3)2]+PF6- and GBI also gives 2+PF6- (81%). The pentamethylcyclopentadienyl analogues [(eta5-C5Me5)Ru(CO)(GBI)]+X- (3+X-; X- = Cl-, BF4-, PF6-, BArf-; 61-84%) are prepared from (eta5-C5Me5)Ru(PPh3)2(Cl), GBI, and CO followed (for the last three) by anion metatheses. An indenyl complex [(eta5-C9H7)Ru(PPh3)(GBI)]+Cl- (96%) is prepared from (eta5-C9H7)Ru(PPh3)2(Cl) and GBI. All complexes are characterized by NMR (1H, 13C, 31P, 19F, 11B), with 2D spectra aiding assignments. Crystal structures of 1+PF6-·CH2Cl2 and 1+BArf-·CH2Cl2 are determined; the anion is hydrogen bonded to the cation in the former. Complexes 1-3+X- are evaluated as catalysts (10 mol %, RT) for condensations of indoles and trans-beta-nitrostyrene. The chloride salts are ineffective (0-5% yields, 48-60 h), but the BArf- salts exhibit excellent reactivities (97-46% yields, 1-48 h), with the BF4- and PF6- salts intermediate. Evidence for hydrogen bonding of the nitro group to the GBI ligand is presented. GBI shows no catalytic activity; a BArf- salt of methylated GBI is active, but much less so than 2-3+BArf-.

A number of 16e two-legged piano-stool complexes [Cp*Ru(PP)] [BAr4] have been prepared by reaction of NaBAr4 with either [Cp*RuCl(PP)] (PP = (PEt3)2, iPr2PCH2CH2PiPr2 (dippe), (PPh3)2) or [Cp*RuCl(PR3)] plus PR3 (PR3 = PMeiPr2, PPhiPr2) in fluorobenzene under argon. The complexes [Cp*Ru(PEt3)2][BAr4], [Cp*Ru(dippe)][BAr4], and [Cp*Ru(PMeiPr2)2] [BAr4] have been structurally characterized by X-ray crystallography. Attempts to isolate analogous species containing other phosphine ligands such as PiPr3, PCy3, and PMe3 led to the sandwich derivative [Cp*Ru(eta6-FPh)] [BAr4], which was also structurally characterized. Both [Cp*Ru(PPh3)2] [BAr4] and [Cp*Ru(PPhiPr2)2] [BAr4] are unstable and rearrange to the 18e sandwich species [Cp*Ru(eta6-C6H5PR2)] [BAr4] and to [Cp*Ru(eta6-C6H5POR2)] [BAr4] (R = Ph, iPr) under trace amounts of oxygen. The geometry of the 16e complexes as well as their affinity for an additional ligand depend on the substituents on the phosphorus. The reactivity with respect to the addition of N2, PR3, O2, H2, and HCl to form 18e derivatives has been studied. Some model systems have been analyzed using density functional theory (DFT) calculations. Also included are comparative studies on the NN counterparts. The moieties [CpRu(PP)]+ (PP = (PH3)2, H2PCH2CH2PH2) adopt typically pyramidal structures (i.e. in the absence of bulky and rigid substituents on P) versus planar structures of [CpRu(NN)]+ (NN = (NH3)2, H2- NCH2CH2NH2). [Cp*Ru(PP)]+ is more stable but has nevertheless a higher affinity of adding a sigma ligand than [Cp*Ru(NN)+.
