Synthetic Route of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

Metal complexes of a series of diphosphorus ligands, 4-(difluorophosphino)-2,5-dimethyl-2H-1,2,3sigma2-diazaphosphole (1), 4-(bis(dimethylaminophosphino)-2,5-dimethyl-2H-1,2,3sigma 2-diazaphosphole (2), and 4-bis(1,1,1-trifluoroethoxyphosphino)-2,5-dimethyl-2H-1,2,3sigma 2-diazaphosphole (3), were prepared. Ligand 1 reacted with CpRu(PPh3)2Cl to give the diastereotopic complex CpRu(PPh3)(1)Cl (4). With CpRh(CO)2 this same ligand gave CpRh(1)2 (5), which was structurally characterized. The Cp-rhodium center carries two difluorophosphinodiazaphole ligands. The P-N bond distances, (1.670(4) and 1.672(3) A), suggest partial multiple-bond character. [Cp*Rh(Cl)2] with (1) gave Cp*Rh(Cl)2(1). Ligand 2 with [Rh(CO)2Cl]2 gave trans-Rh(CO)Cl(2)2 (7), which was structurally characterized. The structure reveals two square-planar isomers in 75:25 ratio differing only in the interchange of Cl and CO. The two diazaphosphole ligands lie trans to each other and the planar diazaphosphole rings are oriented perpendicular to the square plane, stacked so that a mirror plane exists through the Cl-Rh-CO plane. The phosphorus-rhodium distance is 2.33 A. The average P-N bond distance of the exo-phosphorus center and the dimethylamino groups is 1.683 A, shorter than the normally accepted single-bond length. The dimethylamino nitrogen atoms on the exo-phosphorus are planar. Similarly, ligand 3 with [Rh(CO)2Cl]2 gave trans-[Rh(CO)Cl(3)2] (8). The ligand action ranges in reactivity from a similarity to phenylphosphines through to PF3, reflecting the variation in basicity induced by substituent changes on the exo-phosphorus.

A new family of eight ruthenium(II)-cyclopentadienyl bipyridine derivatives, bearing nitrogen, sulfur, phosphorous and carbonyl sigma bonded coligands, has been synthesized. Compounds bearing nitrogen bonded coligands were found to be unstable in aqueous solution, while the others presented appropriate stabilities for the biologic assays and pursued for determination of IC50 values in ovarian (A2780) and breast (MCF7 and MDAMB231) human cancer cell lines. These studies were also carried out for the [5: HSA] and [6: HSA] adducts (HSA = human serum albumin) and a better performance was found for the first case. Spectroscopic, electrochemical studies by cyclic voltammetry and density functional theory calculations allowed us to get some understanding on the electronic flow directions within the molecules and to find a possible clue concerning the structural features of coligands that can activate bipyridyl ligands toward an increased cytotoxic effect. X-ray structure analysis of compound [Ru(eta5-C5H5)(bipy)(PPh3)][PF6] (7; bipy = bipyridine) showed crystallization on C2/c space group with two enantiomers of the [Ru(eta5-C5H5)(bipy)(PPh3)]+ cation complex in the racemic crystal packing.

Electric Literature of 32993-05-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a patent, introducing its new discovery.

A quite general approach for the preparation of eta5- and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl] 2 (arene = C6H6, C10H14 and C6Me6) and eta5- pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5- C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) reacts with two equivalents of the ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) in presence of NH 4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(L1)Cl]PF6 {arene = C6H6 (1), C10H14 (2) and C 6Me6 (3)}, [(eta6-arene)Ru(L 2)Cl]PF6 {arene = C6H6 (4), C 10H14 (5) and C6Me6 (6)}, and [(eta5-C5Me5)M(L1)Cl]PF 6 {M = Rh (7), Ir (8)} and [(eta5-C5Me 5)M(L2)Cl]PF6 {M = Rh (9), Ir (10)}. However the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3) 2Cl], [(eta5-C5H5)Os(PPh 3)2Br], [(eta5-C5Me 5)Ru(PPh3)2Cl] and [(eta5-C 9H7)Ru(PPh3)2Cl] complexes react in presence of one equivalent of ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) and one equivalent of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(L 1)]PF6 (11), [(eta5-C5H 5)Os(PPh3)(L1)]PF6 (12), [(eta5-C5Me5)Ru(PPh3)(L 1)]PF6 (13) and [(eta5-C9H 7)Ru(PPh3)(L1)]PF6 (14) and [(eta5-C5H5)Ru(PPh3)(L 2)]PF6 (15), [(eta5-C5H 5)Os(PPh3)(L2)]PF6 (16), [(eta5-C5Me5)Ru(PPh3)(L 2)]PF6 (17) and [(eta5-C9H 7)Ru(PPh3)(L2)]PF6 (18) respectively. These compounds have been systematically characterized by IR, NMR and mass spectrometry. The molecular structures of 2, 4 and 15 have been established by single crystal X-ray diffraction study and some of the representative complexes have also been studied by UV-visible spectroscopy. The crystal packing diagram of complex 4 reveals that the cation [(eta6-C6H6)Ru(L2)Cl]+ is engaged in non-covalent interaction. This compound gives rise to a 1D helical architecture along the ‘a’ axis via intermolecular NH?Cl hydrogen bonds.

RuCl(dppf)(eta-C5H5) was treated with NH4PF6 in acetonitrile to give the cationic complex PF6 in good yield, in which no bonding interaction between iron and ruthenium atoms was found.The reaction of RuCl(dppf)(eta-C5H5) with terminal acetylene in the presence of NH4PF6 gave the corresponding vinylidene complexes, which were converted on treatment with base or alumina to the corresponding acetylide complexes.A similar reaction with methyl propiolate at room temperature gave the corresponding vinyl ether complex rather than the acetylide complex as a main product, and a novel degradation reaction to the cationic carbonyl complex was also observed.

Tetradentate and ambidentate: Because the four-atom acetylenedithiolate has donor electron density on all sides of the dianion, it can link and electronically couple different metal ions. The bend-back angles of the sulfur atoms in the eta2-C,C?-acetylenedithiolate complex [Tp?W(CO)2(eta2-C2S2)] – are sufficiently flexible to allow for a chelation of both sulfur donors to the {(eta5-C5H5)Ru(PPh 3)} fragment (see structure).

Reactions of the ruthenium complex [Ru]Cl ([Ru]=Cp(PPh3)2Ru; Cp=eta5-C5H5) with several aryl propargyl acetates, each with an ortho-substituted chain of various length containing an epoxide on the aromatic ring and with or without methyl substitutents on the epoxide ring, bring about novel cyclizations. The cyclization reactions of HC?CCH(OAc)(C6H4)CH2(RC2H2O) (R=H, 6 a; R=CH3, 6 b, where RC2H2O is an epoxide ring) in MeOH give the vinylidene complexes 5 a?b, respectively, each with the Cbeta integrated into a tetrahydro-5H-benzo[7]annulen-6-ol ring. A C?C bond formation takes place between the propargyl acetate and the less substituted carbon of the epoxide ring. Further cyclizations of 5 a?b induced by HBF4 give the corresponding vinylidene complexes 8 a?b each with a new 8-oxabicyclo-[3.2.1]octane ring by removal of a methanol molecule in high yield. For similar aryl propargyl acetates with a shorter epoxide chain, the cyclization gives a mixture of a vinylidene complex with a tetrahydronaphthalen-1-ol ring and a carbene complex with a tricyclic indeno-furan ring. For the cyclization of 18, with a longer epoxide chain, opening of the epoxide is required to afford the vicinal bromohydrin 22, then tandem cyclization occurs in one pot. Products are characterized by spectroscopic methods as well as by XRD analysis.

The complexes Ru(eta-RC5H4)Cl(PPh3)2 (R = H, CH3, CH3CO) have been shown to react with the anionic S-S donor ligands M1S2CX, (M1 = Na, K, NH4+; X = OR’, NR”2, CN) to give cyclopentadienyl dithiolate complexes of ruthenium(II).Analogous compounds have been obtained from thallium cyclopentadienide and Ru(S2CX)2(PPh3)2.Ru(eta-CH3COC5H4)Cl(PPh3)2 (III) has been made by reaction between acetylcyclopentadiene, RuCl3(aq.), and PPh3 in absolute ethanol.Complexes of formula Ru(eta-RC5H4)(S2CX)(PPh3)2, with the dithiolate ligand monodentate, are obtained when R = H, X = OC6H11; R = CH3, X = OCH3; R = H, CH3, X = CN.In the other cases studied the isolated complexes contain a bidentate S-S ligand.Steric effects as well as the electronic properties of dithiolate ligands, seem to influence the choice between the two coordination modes.Reaction of III with NaS2CNEt2 affords Ru(S2CNEt2)2(PPh3)2 as the sole product.Carbonylation of complex VI, Ru(eta-C5H5)(S2COC6H11)(PPh3)2 takes place in solution, but the carbonyl complex could not be isolated.

Electric Literature of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

Cyclopentadienyl and pentamethylcyclopentadienyl ruthenium(II) complexes have been synthesized with cyclic (RPCH2NRCH2)2 ligands, with the goal of using these [CpRRu(PR 2NR2)]+ complexes for catalytic O2 reduction to H2O (R = t-butyl, phenyl; R = benzyl, phenyl; R? = methyl, H). In each compound, the Ru is coordinated to the two phosphines, positioning the amines of the ligand in the second coordination sphere where they may act as proton relays to a bound dioxygen ligand. The phosphine, amine, and cyclopentadienyl substituents have been systematically varied in order to understand the effects of each of these parameters on the properties of the complexes. These CpR?Ru(PR 2NR2)+ complexes react with O 2 to form eta2-peroxo complexes, which have been characterized by NMR, IR, and X-ray crystallography. The peak reduction potentials of the O2 ligated complexes have been shown by cyclic voltammetry to vary as much as 0.1 V upon varying the phosphine and amine. In the presence of acid, protonation of these complexes occurs at the pendent amine, forming a hydrogen bond between the protonated amine and the bound O 2. The ruthenium-peroxo complexes decompose upon reduction, precluding catalytic O2 reduction. The irreversible reduction potentials of the protonated O2 complexes depend on the basicity of the pendent amine, giving insight into the role of the proton relay in facilitating reduction.
