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.

Reference 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.

CpRuCl(cod)/NH4PF6 (Cp = cyclopentadienyl, cod = 1,5-cyclooctadiene) is an effective catalyst system for the allylic substitution of cyclic allyl carbonates with nucleophiles. This catalyst system enables the first investigation of the stereochemical course of the ruthenium-catalyzed allylic substitution reaction, in which the reaction proceeds with an overall retention of configuration. The stoichiometric reaction of trans-5-(methoxycarbonyl)cyclohex-2-enyl chloride with Cp*RuCl(cod) (Cp* = pentamethylcyclopentadienyl) gave the unexpected complex Cp*Ru(eta6-C6H5CO2Me) + by the rapid dehydrohalogenation/dehydrogenation of the desired Cp*RuCl2(eta3-C6H8CO 2Me) complex.

A remarkable intermolecular dehydrative coupling reaction with the formation of a C?C bond was found for the vinylidene complex 2 a, yielding the dinuclear bisvinylidene complex 4 a. Complex 2 a containing 1-hydroxyindan moiety was first formed from the reaction of o-propynyl benzaldehyde 1 a with [Ru]?Cl ([Ru]=Cp(PPh3)2Ru) by a cyclization process. For analogous aldehyde 1 b containing an additional 1,3-dioxolane group on the aryl ring, similar intermolecular coupling yields the dinuclear bisvinylidene complex 4 b. However, the fluoro group on the aryl ring in aldehyde 1 c inhibits the coupling reaction, giving only the vinylidene complex 2 c. For the reactions of [Ru]?Cl in MeOH with compounds 1 f, 1 g and 1 h, each with a ketone functionality, cyclization gives vinylidene complexes 2 f, 2 g and 2 h, respectively. However, no similar intermolecular coupling was observed, instead, the intramolecular dehydration yields 8 f, 8 g and 8 h, respectively. In CDCl3, catalytic cyclization is observed for the o-propynylphenyl ketone 1 h with [Ru]?Cl at 50 C giving the isochromene products 14 h. Furthermore, treatment of the o-propynylaryl alpha,beta-unsaturated ketones 1 k?m and 1 n with [Ru]?Cl in MeOH affords the corresponding vinylidene complexes 10 k?m and 11 n each with 1-benzosuberone moiety in the presence of NH4PF6. These intramolecular cyclization products were formed by the addition of Cbeta onto the terminal carbon of the alkene moiety. All these reaction products were characterized by spectroscopic methods. In addition, structures of complexes 4 a, and 10 l were confirmed by single crystal X-ray diffraction analysis.

Seven chain-like trinuclear complexes containing cis-configured central Fe(CN)2 or Fe(NC)2 units attached to two peripheral organometallic units containing Fe, Ru, Cr, or Mn have been synthesized. IR spectra and cyclic voltammograms allow assessment of their electronic situation. Chemical two-electron oxidations were possible for the complexes with Fe(CN-Fe)2 backbones. The oxidized complexes give rise to metal-metal charge transfer bands indicative of significant metal-metal interactions. Their magnetic susceptibilities indicate the absence of magnetic coupling between their two unpaired electrons.

The first spiro cyclic phosphazene containing a nitrile pendant coordinating group, N3P3(O2C12H8) 2(OC6H4CH2CN)2 (1), has been synthesized by the reaction of the spiro cyclophosphazene N3P3(O2C12H8) 2Cl2 with HOC6H4CH2CN and K2CO3 in acetone. The spiro nitrile derivative 1 reacted with CpFe(dppe)I and with CpRu(PPh3)2Cl in the presence of NH4PF6 in CH3OH as solvent to give the complexes {[CpFe(dppe)]2(NCCH2C6H4O) 2N3P3(O2C12H 8)2}(PF6)2 (2) and {[CpRu(PPh3)2]2(NCCH2C 6H4O)2N3P3(O 2C12H8)2}(PF6) 2 (3), respectively. The spectroscopic results indicate that the spiro nitrile derivative behaves like their nitrile ligands. These results have been confirmed by extended Hueckel molecular orbital calculations which have been carried out on the model complexes [CpFe(PH3)2NCCH3]+ (4) and [CpFe(PH3)2(NC-CH2-C6H 4-O)(HO)5N3P3]+ (5). Two metal-to-ligand charge-transfer bands unprecedented in iron-nitrile complexes were observed in the electronic spectrum, as was predicted by the theoretical calculations. The electronic structures of complexes are discussed.

The reaction of rare-earth monoalkyl complexes [Cp2Ln(CH 2SiMe3)(thf)] (Cp = cyclopentadienyl; Ln = Y, Lu) with the ruthenium hydride complex [HRu(dmpe)Cp] (dmpe = bis(dimethylphosphino)ethane) gave the corresponding bimetallic hydride complexes [Cp2Ln(mu-H) (mu-eta1:eta5-C5H4)Ru(dmpe)] (Ln = Y (1a), Lu (1b)). One carbon atom of the Ru-bound Cp ligand bridges to the Ln atom in these complexes. The linkage is formed via a C-H bond activation step. The reaction of 1a with diphenylacetylene led to the formation of [Cp 2Y(mu-H){mu-(Ph)CC(Ph)(C5H4)}Ru(dmpe)], which indicates that the Y-C sigma-bond is significantly more reactive than the Y-H-Ru bond. The reaction of bis(alkyl) complexes [Ln(CH 2SiMe3)2(OC6H3( tBu)2-2,6)(thf)2] (Ln = Y, Lu, tBu = tert-butyl) with [HRu(dmpe)Cp] gave the dimeric products [(OC6H 3(tBu)2-2,6)Ln(mu-H)(mu-eta1: eta5-C5H4){kappa3C,P,P?- CH2(Me)P(CH2)2PMe2}Ru]2 (Ln = Y, Lu) by double C-H bond activation. The complexes were characterized by NMR spectroscopy, X-ray crystal structure analysis (XRD), and elemental analysis.

With [Ru(p-cymene)Cl2]2 as catalyst, diazo-beta-ketoanilides would undergo intramolecular carbenoid arene C-H bond functionalization to afford 3-alkylideneoxindoles in up to 92% yields. The reaction occurs under mild conditions and exhibits excellent chemoselectivity. The lack of primary KIE (kH/kD ? 1) suggests that the reaction should not proceed by rate-limiting C-H bond cleavage; a mechanism involving cyclopropanation of the arene is proposed.

The complexes [CpRuCl(PEt3)2 (1) and [CpRuCl(PMeiPr2)(PPh3)] (2) react with H2S in EtOH in the presence of NaBPh4 furnishing the green persulfide derivatives [{CpRu(L)}2-(mu-S2)][BPh4]2 (L = (PEt3)2, (PMeiPr2)(PPh3)), which were also obtained by reaction of 1 or 2 with elemental sulfur and NaBPh4 in MeOH. At variance with this, the reaction of [Cp*RuCl-(PEt3)2] (3) with H2S in EtOH afforded the RuIV hydrido-metallothiol [Cp*RuH(SH)(PEt3)2]-[BPh4], which has been structurally characterized, derived from the oxidative addition of SH2 to the electron-rich RuII moiety {[Cp*Ru(PEt3)2]+}. This compound is oxidized to yield the persulfide complex [{Cp*Ru(PEt3)2}2(mu-S 2)][BPh4]2, which was also obtained by reaction of 3 with elemental sulfur. The reaction of 1, 2, and 3 with 2-mercapto-pyridine (HSPy) in EtOH yielded cationic complexes in which HSPy is tautomerized to its 1H-pyridine-thione form as inferred from spectral data. Compound 1 reacts with potassium alkyl-xanthates KS2COR (R = Me, Et, iPr) yielding compounds of the type [CpRu(eta1-S2COR)(PEt3)2], whereas the reaction of 2 and 3 led respectively to the complexes [CpRu(eta2-S2COR)(PMeiPr2)] and [Cp*Ru(eta2-S2COR)(PEt3)], which contain one bidentate xanthate and one phosphine. The X-ray crystal structure of [Cp*Ru(S2COiPr)(PEt3)] was determined. In analogous fashion, the reaction of 1 with sodium diethyldithiocarbamate yielded [CpRu(eta1-S2CNEt2)(PEt3) 2], whereas 2 and 3 afforded the corresponding derivatives [CpRu(eta2-S2CNEt2)(PMeiPr 2)] and [Cp*Ru(eta2-S2CNEt2)(PEt3)].
