Syntheses, characterization and structure determination of {[CpRu(X)]2(eta2,mu2-dppe)2} complexes (X=Cl, N3; Dppe=Ph2PCH2CH2PPh2): Chelating vs. bridging behavior of a classical bidentate ligand

Phosphine substitution reactions between (eta5-C5H5)Ru(PPh3)2Cl (1) and 1,2-bis(diphenylphosphino)ethane (Ph2P(CH2)2PPh2, dppe), in refluxing benzene or in toluene at 80C afforded a mixture of complexes where dppe behaves both as a bridging and as a chelating ligand. CpRu(eta2-dppe)Cl (2) and {[CpRu(Cl)]2(eta2,mu2-dppe)2} (3) were separated by fractional precipitation from the reaction mother-liquor, and were characterized by 1H, 13C, 31P NMR, elemental analysis and IR spectroscopy. The (2):(3) ratio in the composition of the reaction product was found to be independent of the reaction time. In solution and at room temperature, (3) exists in both boat and chair conformers of a 10-membered ring, while at lower temperatures, and in the solid-state, only the chair conformer is observed. Compounds (2) and (3) undergo halide-displacement upon reacting with NaN3 in the presence of ethanol to yield CpRu(eta2-dppe)(N3) (4) and {[CpRu(N3)]2(eta2,mu2-dppe) 2} (5), respectively. The crystal structures of (3) and (5) were determined. Elsevier Science Ltd.

Study of novel eta5-cyclopentadienyl and eta6-arene platinum group metal complexes containing a N4-type ligand and their structural characterization

The mononuclear eta5-cyclopentadienyl complexes [(eta5-C5H5)Ru(PPh3)2Cl], [(eta5-C5H5)Os(PPh3)2Br] and pentamethylcyclopentadienyl complex [(eta5-C5Me5)Ru(PPh3)2Cl] react in the presence of 1 eq. of the tetradentate N,N?-chelating ligand 3,5-bis(2-pyridyl)pyrazole (bpp-H) and 1 eq. of NH4PF6 in methanol to afford the mononuclear complexes [(eta5-C5H5)Ru(PPh3)(bpp-H)]PF6 ([1]PF6), [(eta5-C5H5)Os(PPh3)(bpp-H)]PF6 ([2]PF6) and [(eta5-C5Me5)Ru(PPh3)(bpp-H)]PF6 ([3]PF6), respectively. The dinuclear eta5-pentamethylcyclopentadienyl complexes [(eta5-C5Me5)Rh(mu-Cl)Cl]2 and [(eta5-C5Me5)Ir(mu-Cl)Cl]2 as well as the dinuclear eta6-arene ruthenium complexes [(eta6-C6H6)Ru(mu-Cl)Cl]2 and [(eta6-p-iPrC6H4Me)Ru(mu-Cl)Cl]2 react with 2 eq. of bpp-H in the presence of NH4PF6 or NH4BF4 to afford the corresponding mononuclear complexes [(eta5-C5Me5)Rh(bpp-H)Cl]PF6 ([4]PF6), [(eta5-C5Me5)Ir(bpp-H)Cl]PF6 ([5]PF6), [(eta6-C6H6)Ru(bpp-H)Cl]BF4 ([6]BF4) and [(eta6-p-iPrC6H4Me)Ru(bpp-H)Cl]BF4 ([7]BF4). However, in the presence of 1 eq. of bpp-H and NH4BF4 the reaction with the same eta6-arene ruthenium complexes affords the dinuclear salts [(eta6-C6H6)2Ru2(bpp)Cl2]BF4 ([8]BF4) and [(eta6-p-iPrC6H4Me)2Ru2(bpp)Cl2]BF4 ([9]BF4), respectively. These compounds have been characterized by IR, NMR and mass spectrometry, as well as by elemental analysis. The molecular structures of [1]PF6, [5]PF6 and [8]BF4 have been established by single crystal X-ray diffraction studies and some representative complexes have been studied by UV-vis spectroscopy.

Polycarbon Ligand Chemistry: Electronic Interactions between a Mononuclear Ruthenium Fragment and a Cobalt-Carbon Cluster Core

The preparation, characterization, and electrochemical response of the complexes Co2(mu-Me3SiC?CC2C?CSiMe 3)(CO)4(dppm) (2) and Co2(mu-Me3SiC2C?CC?CSiMe 3)(CO)4(dppm) (3) are described. Metalation of one of the pendant alkynyl groups in each complex has been achieved, yielding Co2{mu-Me3SiC?CC2C?C[Ru(PPh 3)2Cp]}(CO)4(dppm) (4) and Co2{mu-Me3-SiC2C?CC?C[Ru(PPh 3)2Cp]}(CO)4(dppm) (5). The spectral and electrochemical properties of the heterometallic complexes indicate a significant electronic interaction between the mononuclear fragment and the metallocarbon cluster core. The electronic structure of these compounds has been modeled using DFT, ZINDO, and ELF calculations, and an explanation of the nature of the electronic interaction between the heterometallic fragments is presented.

Cyclopentadienyl RuII Complexes as Highly Efficient Catalysts for the N-Methylation of Alkylamines by Methanol

The ruthenium(II) half-sandwich complex [RuCl(eta5-C5H5)(PPh3)2] (1) catalyses the reaction between methanol and alkylamines RNH2 or R1R2NH to afford RN(CH3)2 and R1R2NCH3 products, respectively. The reaction is quantitative and generally fast, at the methanol reflux temperature, for a wide spectrum of substrates. Starting form primary amines, the stepwise formation of RN=CH2, RNHCH3, and RN(CH3)2 has been observed. Both PPh3 and Cl- dissociation from 1 are key-steps in forming the effective catalytic species. The catalytic activity of several half-sandwich neutral or cationic complexes (2-15) related to 1 is also discussed.

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

Correlation between Structural and Solution Calorimetric Data for Cp*Ru(PR3)2Cl (Cp* = C5Me5) Complexes

Single-crystal X-ray diffraction studies were conducted on the following compounds: Cp*Ru(PMe3)2Cl (1), Cp*Ru(PPhMe2)2Cl (2), Cp*Ru(PMePh2)2Cl (3), Cp*Ru(PPh3)2Cl (4), Cp*Ru(PEt3)2Cl (5), Cp*Ru(AsEt3)2Cl (6), Cp*Ru(PnBu3)2Cl (7), and Cp*Ru(dmpm)Cl (8). Structural information obtained from these X-ray studies can be correlated with enthalpies of ligand substitution previously determined from solution calorimetry. The cone angle of the phosphine ligand (monodentate) and the Ru-P bond distance were found to be proportional to the enthalpy of reaction.

New bis(phosphines) derived from N,N?-substituted ethylenediamine derivatives. Synthesis and transition metal chemistry of X2PN(R)CH2CH2(R)NPX2 (R = CH2Ph or Ph, X = Ph; R = CH2Ph, X2 = O2C6H4).

The bis(phosphines) of the type X2PN(R)CH2CH2(R)NPX2 (R = Ph or CH2Ph, X = Ph; R = CH2Ph, X2 = O2C6H4) with the ethylenediamine framework were prepared by reaction of X2PCl with the corresponding N,N?-substituted ethylenediamine derivatives. These ligands readily formed complexes with Group 6 metals and RuII, NiII, PdII and PtII. All complexes were characterised by elemental analysis, IR and NMR spectroscopic methods of which 31P-{1H} is most valuable. The structures of the bis(phosphine) ligand Ph2PN(CH2Ph)CH2CH2(CH 2Ph)NPPh2 and its platinum(II) complex cis-[PtCl2{PPh2N(CH2Ph)CH2CH 2(CH2Ph)NPPh2}] were determined by X-ray crystallography. The ligand crystallises in the extended conformation with both the nitrogen atoms nearly planar and the bond angles around them close to 120. The P-N distances are shorter than normally accepted P-N single bond lengths (ca. 1.77 A) suggesting some degree of P-N pi bonding. The seven-membered chelate ring in the platinum complex is non-planar but the metal atom is in a typical square planar environment with two phosphorus atoms and two chlorine atoms in a mutually cis disposition and the ethylenediamine bridge is folded with respect to the plane in an “open envelope” fashion.

Highly selective organometallic ruthenium catalysts for aldehyde olefination

Complexes of general formula (eta5-L)RuCl(PR3)2 are shown to be active and highly selective catalysts for the olefination of aldehydes in the presence of phosphines and diazoacetate at moderate temperatures. With equal catalyst loadings of Cp*RuCl(PR3) 2 shows comparable activity and higher selectivity with regard to the most active catalysts known to date for this reaction. Spectroscopic investigations demonstrate that the reaction mechanism includes the quantitative formation of the corresponding phosphorus ylide from the preformed phosphazine.

Syntheses and molecular structures of group 8 benzonitrile complexes

The molecular structures of eight nitrile complexes of general form [M(NCC6H4R-4)(L2)Cp?]PF6 [M = Fe, Ru; L2 = dppe, (PPh3)2; Cp? = Cp, Cp*] are reported and discussed in terms of the nature of the M-N interaction. Data are consistent with a predominantly sigma-interaction, similar to that found in related acetylide complexes, with little evidence for metal to nitrile pi-back bonding interactions.
