The synthesis of polyaryl phosphonium salts by cyclotrimerization of aryl alkynes is induced by a stoichiometric amount of the ruthenium eta5-pentadienyl complex (eta5-C5H7)(PPh3)2RuCl (1). With only 1 mol % quantity, complex 1 efficiently catalyzed the dimerization of aryl alkynes at room temperature to afford the corresponding (Z)-1,4-diarylbut-1-en-3-yne derivatives as the major products.

The vinylidene complex [Ru(eta5-C5H 5)(PPh3)2(CCHUr)][X] (X = PF6, OTf, Ur = uracil) is a versatile precursor for a range of organometallic complexes containing pendant uracil groups. Using appropriate conditions the vinylidene complex may be selectively transformed into alkynyl Ru(-CCUr)(eta5- C5H5)(PPh3)2, carbene [Ru(eta5-C5H5)(PPh3) 2(C{OMe}-CH2Ur)][X] and alkenyl-phosphonio species [Ru(E-CHC{PPh3}Ur)(eta5-C5H 5)(PPh3)2][X]. The synthesis of the related alkenyl-phosphonio complexes [Ru(E-CHC{PPh3}R)(eta5- C5H5)(PPh3)2][X] (R = Ph, C 6H4-3-OMe) is described; these undergo a further orthometallation reaction: the mechanism of this latter reaction appears to proceed via dissociation of a ruthenium-bound PPh3 ligand.

Reaction of monophosphinite ligand, 2-(diphenylphosphinoxy)naphthyl, C 10H7OPPh2 (1) with elemental sulphur or selenium gives the corresponding sulphide C10H7OP(S) Ph2 (2) or selenide C10H7OP(Se)Ph2 (3) derivatives. Reaction of 1 with [CpRu(PPh3)2Cl] gives monosubstituted complex, [CpRu(C10H7OPPh 2)(PPh3)(Cl] (4) as well as the disubstituted complex, [CpRu(C10H7OPPh2)2Cl] (5) depending upon the reaction conditions. Treatment of 1 with [Rh(CO)2Cl] 2 affords a trans-complex, [Rh(CO)(C10H 7OPPh2)2Cl] (6). Reaction of 1 with [Pd(COD)Cl2] results in the formation of an unexpected chloro-bridged dipalladium complex; [Pd(PPh2O)(PPh2OH)(mu-Cl)] 2 (7), whereas similar reaction with [Pt(COD)Cl2] gives cis-[Pt(C10H7OPPh2)2Cl2] (8) in good yield.

32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 32993-05-8, Recommanded Product: 32993-05-8

The new ruthenium hydride complexes CpRuH(L) (L = PR2CH2CH2PR2, R = p-CF3C6H4 (dtfpe) or R = p-MeOC6H4 (dape)) were prepared by reaction of NaOMe with CpRuCl(L), which were obtained by treating CpRuCl(PPh3)2 with L. Similarly, Cp*RuH(L) (L = dppm, (PMePh2)2) were prepared from the reaction of NaOMe with Cp*RuCl(L) obtained from the reaction of Cp*RuCl2 with L in the presence of Zn. Protonation of CpRuH(L) (L = dtfpe, dape) and Cp*RuH(dppm) with HBF4-Et2O produces mixtures of [CpRu(H)2(L)]+ and [CpRu(eta-H2)(L)]+, and [Cp*Ru(H)2(dppm)]+ and [Cp*Ru-(eta2-H2)(dppm)]+. The pKa values of the dihydrogen/dihydride complexes [CpRuH2(L)]+ (L = dtfpe, dppm, dppe, (PPh3)2, dppp, dape) and [Cp*RuH2(L)]+ (L = dppm, (PMePh2)2) are determined by studying acid/base equilibria by 1H and 31P NMR spectroscopy in both CH2Cl2 and THF. The electrochemical properties of the monohydrido complexes CpRuH(L) and Cp*RuH(L) are reported. Peak potentials for oxidation of these monohydrides and pKa values of the cationic complexes are linearly related for all the complexes with a dihydrogen form: pKa(Ru(H2)+) = -10.7Epa(RuH+/RuH) + 13.0. As expected eta2-H2 acidity decreases as the parent hydride becomes easier to oxidize. The related complexes with just a dihydride form, [CpRu(H)2(L)]+ (L = (PPh3)2, dppp) and [Cp*Ru(H)2(PMePh2)2]+, give a similar trend. Acidity constants have been determined for both tautomers when they observed; the pKa of the eta2-H2 form is ?0.3 pKa unit less (more acidic) than that of the (H)2 form for the complexes with L = dtfpe, dppe, and dape but is 0.4 unit greater for [Cp*RuH2(dppm)]+. The acidities of the two tautomers are similar because their concentrations are similar and they have the same monohydrido conjugate base. Other trends in pKa, 1J(HD), and deltaRu(H2) values of dihydrogen complexes and ratio of dihydride to dihydrogen tautomers and the peak potentials for oxidation of the monohydrido complexes are presented. These correlations are shown to be of value in explaining/predicting the propensity of dihydrogen to undergo heterolytic cleavage. Extremes in pKa values of such cyclopentadienylruthenium(Il) complexes are expected for [Cp*RuH2(dmpe)]+ (pKa ? 12) and [CpRuH2(CO)2]+ (pKa ? -6).

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 1:1 stoichiometric reactions of 3-methoxy salicylaldehyde-4(N)-substituted thiosemicarbazones (H2L1?4) with [RuCpCl(PPh3)2] was carried out in methanol. The obtained complexes (1?4) were characterized by analytical, IR, absorption and 1H NMR spectroscopic studies. The structures of ligand [H2-3MSal-etsc] (H2L3) and complex [RuCp(Msal-etsc) (PPh3)] (3), were characterized by single crystal X-ray diffraction studies. The interaction of the ruthenium(II) complexes (1?4) with calfthymus DNA (CT-DNA) has been explored by absorption and emission titration methods. Based on the observations, an intercalative binding mode of DNA has been proposed. The protein binding abilities of the new complexes were monitored by quenching the tryptophan and tyrosine residues of BSA, as model protein. From the studies, it was found that the new ruthenium metallacycles exhibited better affinity than their precursors. The free radical scavenging assay suggests that all complexes effectively scavenged the DPPH radicals as compared to that of standard control ascorbic acid and scavenging activities of complexes are in the order of 4 > 2 > 3 > 1. In addition, ruthenium(II) complexes (2?4) also exhibited an excellent in vivo antioxidant activity as it was able to increase the survival of worms exposed to lethal oxidative and thermal stresses possibly through reducing the intracellular ROS levels. It was interesting to note that complexes 2?4 failed to increase the lifespan of mev-1 mutant worms having shortened lifespan due to the over production of free radicals. This data confirmed that complexes 2?4 conferred stress resistance in C. elegans, but they also require an endogenous detoxification mechanism for doing so. The genetic and reporter gene expression analysis revealed that complexes 2?4 maintained the intracellular redox status and offered stress protection through transactivation of antioxidant defence machinery genes gst-4 and sod-3 which are directly regulated by SKN-1 and DAF-16 transcription factors, respectively. Altogether, our results suggested that complexes 2?4 might play a crucial role in stress modulation and they perhaps exert almost similar effects in higher models, which is an important issue to be validated in future.

The rate constants for hydride transfer from CpRu(P-P)H (P-P = bis(diphenylphosphino)-methane (dppm), bis(diphenylphosphino)ethane (dppe), bis(diphenylphosphino)benzene (dpbz), or bis(diphenylphosphino)propane (dppp)) to 1-(1-phenylethylidene)pyrrolidinium tetrafluoroborate have been measured. The bite angles of the hydride complexes CpRu-(dppm)H, CpRu(dppe)H, CpRu(dpbz)H, and CpRu(dppb)H (dppb = bis(diphenylphosphino)-butane) have been determined by X-ray diffraction. Hydride transfer is faster when the chelate ring of the diphosphine is smaller (i.e., CpRu(dppm)H > CpRu(dppe)H ? CpRu(dpbz)H > CpRu(dppp)H ? CpRu(dppb)H). Boiling CpRu(PPh3)2Cl with dpbz in benzene or toluene results in the formation of [CpRu(PPh3)(eta2-dpbz)]Cl as well as CpRu(dpbz)Cl.

A series of Cp’Ru(PR3)(PPh3)Cl complexes, where Cp? = Cp*, Dp, Ind, Cp, Tp and PR3 = PTA, PMe3, PPh3, have been used to catalyze the atom transfer radical addition (ATRA) of various chloro substrates (CC14, CHC1 3, and TsCl) to styrene and/or hexene. The complexes Cp *Ru(PTA)(PPh3)Cl, Cp*Ru(PMe 3)(PPh3)Cl, DpRu(PMe3)(PPh3)Cl, and TpRu(PMe3)(PPh3)Cl have been synthesized by ligand exchange reactions with Cp?Ru(PPh3)2Cl and characterized by NMR spectroscopy and X-ray crystallography. An alternative synthesis for CpRu(PMe3)(PPh3)Cl and the solid-state structure of the previously reported complex IndRu(PMe3)(PPh 3)Cl are also described. Among the ruthenium(II) complexes studied, Cp*Ru(PTA)(PPh3)Cl and Cp *Ru(PMe3)(PPh3)Cl were very active at 60 C with TOF values of 1060 and 933 h-1, respectively; Cp *Ru(PPh3)2Cl was the most active for the addition of CCI4 to styrene with a TOF > 960 h-1 at room temperature. Total turnovers (TTO) in excess of 80000 for the addition of CC14 to hexene were obtained for the Cp* complexes, making these complexes the most active and robust catalysts for ATRA reported to date.
