Five ruthenium(II) complexes of the type (eta5-C5H5)Ru(PPh3)(beta-diket) have been synthesised.The structure of these chelated beta-diketonates is assigned from IR and PMR spectral data.A tetrahedral geometry around ruthenium has been suggested for these complexes, similar to that of the starting compound (eta5-C5H5)Ru(PPh3)2Cl.

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.Computed Properties of C41H35ClP2Ru, you can also check out more blogs about32993-05-8

The complexes LnM-CN-Ag-CN with LnM=Cp(dppe)Fe or Cp(PPh3)2Ru are available from [Ag(CN)2]- and [LnM]+ or LnM-CN. They are precursors of [LnM-CN-Ag-NC-MLn]+. Likewise the trinuclear complexes [LnM?-CN-Ag-NC-M?Ln]+ with LnM?=(TPA)Cu and cis-(bpy)2FeCN have been prepared. Irrespective of the CN attachment in the starting materials the cyanide-bridged compounds always contain M-CN-Ag arrays, i.e. silver-isocyanide coordination, thereby proving the lability of the silver-cyanide linkage. Electrochemical measurements have shown that there is no electronic communication between the outer metal centers in the trinuclear complexes.

Two ruthenium acetylide complexes [Ru]C?C(C5H 3RN) (1a, R = H; 1b, R = Me; [Ru] = Cp(PPh3) 2Ru) containing 2-pyridyl groups are prepared and their chemical reactivities are explored. Protonation of the ruthenium acetylide complex 1a with HBF4 takes place at both the nitrogen atom and Css, giving the dicationic pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H 4NH)}(BF4)2 (3a). Addition of BF3 to la yields the Lewis acid/base adduct [Ru]OC(C5H4N? BF3) (4a). In the presence of moisture both complexes 3a and 4a in solution transform into the cationic heterocyclic carbene complex {[Ru]=C(O)CH2(C5H4N?BF2)}BF4 (6a), for which the structure is confirmed by X-ray structure determination. The formation of 6a involves the intermediate {[Ru]=C=C(H)(C5H 4N?BF2OH)}BF4 (5a), characterized by spectroscopic methods. DFT calculations show that the Gibbs free energy change of the exothermic transformation of 5a to 6a is -20.59 kcal/mol. N-Alkylation reactions of 1b with two alkyl bromides BrCH2R? (R? = CH=CHCO2Me and CO2Me) yield two pyridiniumacetylide complexes {[Ru]C? C(C5H3MeNCH2R?)} Br (7b, R? = CH=CHCO2Me; 7c, R? = CO2Me, respectively). Complex 7c, characterized by X-ray structure determination, undergoes further protonation to give the pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H4NCH2R?)2+ (8c). Interestingly, the acetylide complex 7b undergoes a C-C coupling reaction of the acetylic Css with the C=C double bond to give the vinylidene complex 9b, characterized also by X-ray structure determination.

Cationic ruthenium sulfine complexes [CpRu(PR?3)2(O=S=CHR)]PF6 have been obtained by a variety of methods. Oxidation of the thioaldehyde complexes [CpRu(PR?3)2(S=CHR)]PF6 with either 2-tosyl-3-phenyl-oxaziridine (PR?3 = PMe3) or magnesium-monoperoxyphthalate (PR?3 = 1/2 dppm) gave complexes of arylsulfines (R = Ph, 3-C6H4F, 4-C6H4Cl, 4-C6H4OMe) selectively in their thermodynamically less stable E form. Siloxane elimination from the sulfinato complexes [CpRu(PMe3)2(SO2CHRSiMe3)] yielded complexes of aliphatic sulfines, [CpRn(PMe3)2(O=S=CHR)]PF6 (R = H, Me). Treatment of [CpRu(dppm)(SO2CH2R)] with acetyl chloride led to an oxygen redistribution giving complexes of thioaldehydes [CpRu(dppm)(eta2-S=CH2)]PF6 and [CpRu(dppm)(eta1-S=CHR)]PF6 (R = Ph, 4-C6H4Cl). The structure of the latter was determined by X-ray crystallography. The loss of oxygen can be suppressed by performing the acylation-elimination sequence in the presence of poly-(4-vinylpyridine). This provided a selective access to complexes of Z-sulfines, [CpRu(PMe3)2(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl) and [CpRu(dppm)(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl, COOEt, Cl). Complexes of the parent sulfine O=S=CH2 were also obtained by SO transfer to the methylene complex [CpRu(PMe3)2(CH2)]PF6 and methylene transfer to the sulfur monoxide complex [Cp*Ru(PMe3)2 (SO)]PF6. Most of the new sulfine complexes exhibit dynamic behaviour in solution, i. e. ligand rotation, ligand inversion, and eta2/etaI hapticity change. O-Alkylation provided the dicationic complex [CpRu(PMe3)2 (EtO-S=CHMe)](PF6)2, and S-oxidation gave the sulfene complexes [(C5R5)Ru(PMe3)2 (O2S=CH2)]PF6 (R = H, Me).

In this study, ruthenium(ii)-catalyzed direct hydrosilylation of internal alkynes with high regio-selectivity and stereo-selectivity is reported. This title transformation led to various vinylsilanes in good to excellent yields. This approach features mild reaction conditions, low catalyst loading, air-stability, and good functional group tolerance. Furthermore, gram-scale preparation and some transformations of vinylsilanes were carried out, which further underscored its synthetic utility and applicability.

Reaction of benzaldehyde thiosemicarbazones [H2LR, where H 2 stands for the two protons, the hydrazinic proton, and the phenyl proton at the ortho position, with respect to the imine function and R (R = OCH3, CH3, H, Cl, and NO2) for the para substituent] with [Ru(PPh3)2(CO)2Cl 2], carried out in refluxing ethanol, afforded monomeric complexes of type [Ru(PPh3)2(CO)(HLR)(H)]. The crystal structure of the [Ru(PPh3)2(CO)(HLNO2)(H)] complex was determined. The thiosemicarbazone ligand is coordinated to the ruthenium center as a bidentate N,S-donor ligand forming a four-membered chelate ring. When the reaction of the thiosemicarbazones with [Ru(PPh3)2(CO) 2Cl2] was carried out in refluxing toluene, a family of dimeric complexes of type [Ru2(PPh3) 2(CO) 2(LR)2] were obtained. The crystal structure of [Ru 2(PPh3)2(CO)2(LCl)2] was determined. Each thiosemicarbazone ligand is coordinated to one ruthenium atom, by dissociation of the two protons, as a dianionic tridentate C,N,S-donor ligand, and at the same time the sulfur atom is also bonded to the second ruthenium center. 1H NMR spectra of the complexes of both types are in excellent agreement with their compositions. All the dimeric and monomeric complexes are diamagnetic (low-spin d6, S = 0) and show intense absorptions in the visible and ultraviolet regions. Cyclic voltammetry of the [Ru(PPh3)2(CO)(HLR)(H)] and [Ru2(PPh 3)2-(CO)2(LR)2] complexes show the ruthenium(II)-ruthenium(III) oxidation within 0.48-0.73 V vs. SCE followed by a ruthenium(III)-ruthenium(IV) oxidation within 1.09-1.47 V vs. SCE. Potentials of both the oxidations are found to correlate linearly with the electron-withdrawing character of the substituent R. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
