Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), category: ruthenium-catalysts.

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-.

Reaction of the ruthenium half sandwich compound RuCl(eta5- C5H5)(PPh3)2 with the uracil (Ur) substituted alkyne HCCUr in the presence of halide scavengers NH4X (X = PF6, BF4, OTf) results in the formation of the vinylidene complexes [Ru(CCHUr)(eta5-C5H 5)(PPh3)2][X] which crystallize in the hexagonal space group P6(3)/m. The hexagonal symmetry inherent to the system is due to the formation of a hydrogen bonded array mediated by the two sets of donor-acceptor units on the uracil, resulting in the formation of a cyclic “rosette” containing six ruthenium cations. In solution the 1H and 31P{1H} NMR spectra of the vinylidene complexes are both concentration and temperature dependent, in accord with the presence of monomer-dimer equilibria in which the rate of rotation of the vinylidene group is fast on the NMR timescale in the monomeric species, but slow in the dimers. The isoelectronic molybdenum-containing vinylidene complex [Mo(eta7-C7H7)(dppe)(CCHUr)][BF4] (dppe = 1,2-bis(diphenylphosphino)ethane) has also been prepared, but forms symmetric dimers in the solid state.

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.

Ruthenium-assisted cyclizations of two enynes, HC?CCH(OH)(C 6H4)X-CH2CH=CMe2 (X=S (1 a), O (1 b)), each of which contains two terminal methyl substituents on the olefinic parts, are explored. The reaction of 1 a in CH2Cl2 gives the vinylidene complex 2 a from the first cyclization and two side products, 3 a and the carbene complex 4 a with a benzothiophene ligand. The same reaction in the presence of HBF4 affords 4 a exclusively. Air oxidation of 4 a in the presence of Et3N readily gives an aldehyde product. In MeOH, tandem cyclizations of 1 a generate a mixture of the benzothiochromene compound 10 a and the carbene complex 7 a also with a benzothiochromene ligand. First, cyclization of 1 b likewise proceeds in CH2Cl2 to give 2 b. Tandem cyclization of 1 b in MeOH yields comparable products 10 b and 7 b with benzochromene moieties, yet with no other side product. The reaction of [Ru]Cl with HC?CCH(OH)(C6H4)S-CH2CH= CH2 (1 c), which contains no methyl substituent in the olefinic part, in MeOH gives the carbene complex 15 c with an unsubstituted thiochromene by means of a C-S bond formation. Structures of 3 a and 15 c are confirmed by X-ray diffraction analysis. The presence of methyl groups of enynes 1 a and 1 b promotes sequential cyclization reactions that involve C-C bond formation through carbocationic species. Copyright

The complex [RuCl(eta5-C5H5){PPh2(2-MeC 6H4)}2] (1), unlike the triphenylphosphine analog [RuCl(eta5-C5H5)(PPh3) 2], reacts under mild conditions with CO, N2CPh2 and HC?CPh to give the neutral carbonyl, carbene and vinylidene derivatives [RuCl(eta5-C5H5)(L){PPh 2(2-MeC6H4)}] (L = CO 2, CPh2 5, C=CHPh 6), respectively, via displacement of one phosphine ligand. The vinylidene complex 6 promptly reacts with benzylamine affording the aminocarbene [RuCl(eta5-C5H5){=C(NHCH 2Ph)CH2Ph} {PPh2(2-MeC6H4)}] (7). Moreover, the cyclometalated derivative [Ru(eta5-C5H5){PPh2(2-CH 2C6H4)}{PPh2(2-MeC6H 4)}] (4) has been obtained from the methyl complex [RuMe(eta5-C5H5){PPh2(2-MeC 6H4)}2] (3) by intramolecular C-H bond cleavage and methane elimination. Complex 1, whose X-ray structure analysis is also reported, has been found to catalyze alkyne coupling reactions.

Electric Literature of 32993-05-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.

The activity of chloro(eta5-cyclopentadienyl)(didentate phosphine)ruthenium(II) complexes in the catalysis of two types of reaction with allylic alcohols is described. The isomerisation of 3-buten-2-ol to butanone (MEK) and allyl alcohol to propanal proceeds at high rates. A trend in catalytic activity is observed upon variation of the carbon-chain length in the didentate phosphine ligand: dppm < dppe < dppp < dppb. Complexes with rigid didentate phosphine ligands like cis-dppv and dppph show no activity. The second type of reaction constitutes the first example of a ruthenium-catalysed ether formation directly from allylic alcohols. Homo-coupled ethers like di-allyl ether (DAE) are easily formed as well as ethers from heterocoupling of allyl alcohol with aromatic and aliphatic alcohols. In fact, the ruthenium complexes achieve much higher turnover frequencies and turnover numbers than reported before in palladium-catalysed ether formation. Complexes with dppe and dppp in the presence of a conjugated diene switch from isomerisation to ether formation, but the new complex [RuClCp(o-MeO-dppe)] (Cp = eta5-cyclopentadienyl) (3) has proven to be very active in ether formation, even in the absence of a diene. The mechanisms of the reactions have been studied by using both deuterium-labelled substrates and 31P nuclear magnetic resonance (NMR). (C) 2000 Elsevier Science B.V.

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.
