Ruthenium-catalyzed cycloaddition of alkynes and organic azides

Cp*RuCl(PPh3)2 is an effective catalyst for the regioselective “fusion” of organic azides and terminal alkynes, producing 1,5-disubstituted 1,2,3-triazoles. Internal alkynes also participate in this catalysis, resulting in fully substituted 1,2,3-triazoles. Copyright

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.

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.

Coupling H2 to Electron Transfer with a 17-Electron Heterobimetallic Hydride: A “Redox Switch” Model for the H2-Activating Center of Hydrogenase

A meta-stable heterobimetallic mixed-valence ion, , is formed by the one-electron oxidation of Cp*(dppf)RuH <1, dppf = 1,1'-bis(diphenylphosphino)ferrocene, Cp* = pentamethylcyclopentadienide>.A remarkable stability toward one-electron oxidation is revealed by the cyclic voltammetry of 1 which contains two reversible oxidations at +0.073 and +0.541 V and a quasireversible oxidation at +0.975 V (vs NHE assigned to Ru(III/II), Ru(IV/III), and Fe(III/II), respectively.The isolable Ru(III) metal hydride, PF6 (1+), is characterized by a NIR absorption at 912 nm (epsilon = 486 M-1A cm-1) assigned to an intervalence transfer band and a series of atom transfer reactions yielding the even electron derivatives PF6 (X = H, Cl, Br, I).A crystallographically determined Fe-Ru distance of 4.383(1) Angstroem in 1 is consonant with the classification of 1+ as a weakly coupled.Type II mixed-valence ion (Hab = 627 cm-1, alpha2 = 3.3×10-3).This is the first reported example of a mixed-valence bimetallic complex containing the widely used dppf ligand.The ability of 1 to serve as a heterobimetallic catalyst for the reduction of methyl viologen with H2 makes it a unique functional model of hydrogenase enzymes.

Novel structural rearrangements induced by metal-metal interactions in ruthenium(II) ruthenocenyl- and (pentamethylruthenocenyl)acetylide complexes, RcC?CRuL2(eta5-C5R5) and Rc?C?CRuL2(eta5-C5R5)

The reaction of RcC?CH [Rc = (eta5-C5H5)Ru(eta5-C 5H4)] with RuCIL2(eta5-C5R5) [R = H or Me; L2 = 2PPh3 or Ph2PCH2CH2PPh2 (dppe)] in the presence of NH4PF6 and subsequent treatment with base gave Ru(II) ruthenocenylacetylide complexes RcC?CRuL2(eta5-C5R5) in good yields. In a similar manner, the pentamethylruthenocene analogues, Rc?C?CRuL2(eta5-C5R5) [Rc? = (eta5-C5Me5)Ru(eta5-C 5H4)], were also prepared. Cyclic voltammograms of the complexes showed two reversible one-electron-oxidation processes, consisting of the processes [Ru(II)Ru?(II] to [Ru(III)Ru?(II] and then to [Ru(III)Ru?(III)]. Chemical oxidation of the complexes induced novel structural rearrangement. The two-electron oxidation of complex RcC?CRu(PPh3)2(eta5-C5H 5) afforded a kind of allenylidene complex, a cyclopentadienyl-idenethylidene complex, [(eta5-C5H5)Ru{mu-eta 6:eta1-C5H4C=C}Ru(PPh 3)2(eta5-C5H5)] 2+, in 90% yield. The one-electron oxidation of Rc?C?CRu(PPh3)2(eta5-C 5H5) gave the vinylidene complex (Rc?CH=C)Ru(PPh3)2(eta5-C 5H5) in 62% yield, while the two-electron oxidation led to the fulvene-vinylidene complex [(eta6-C5Me4CH2)Ru{mu-eta 5:eta1-C5H4CH=C}Ru(PPh 3)2(eta5-C5R5)] 2+ by an intramolecular hydrogen transfer in 59% yield.

Grafting of cyclopentadienyl ruthenium complexes on aminosilane linker modified mesoporous SBA-15 silicates

Cyclopentadienyl ruthenium phosphane and carbene complexes are grafted on the surface of mesoporous SBA-15 molecular sieves through an aminosilane linker. The nature of the support after the grafting is examined by powder XRD, TEM and N2 adsorption/desorption analysis. Elemental analysis, FT-IR, DRIFTS, TG-MS and MAS-NMR studies confirm the successful grafting of the complexes on the surface. The grafted materials are applied for catalytic aldehyde olefination and cyclopropanation. The Royal Society of Chemistry.

Study of half sandwich platinum group metal complexes containing tetradentate N-donor ligand bearing two di-pyridylamine units linked by an aromatic spacer

A general approach for the preparation of dinuclear eta5- and eta6-cyclic hydrocarbon platinum group metal complexes, viz. [(eta6-arene)2Ru2(NN?NN)Cl 2]2+ (arene = C6H6, 1; p- iPrC6H4Me, 2; C6Me6, 3), [(eta5-C5Me5)2M 2(NN?NN)Cl2]2+ (M = Rh, 4; Ir, 5), [(eta5-C5H5)2M2(NN?

The cationic dinuclear complexes have been isolated as their hexafluorophosphate or hexafluoroantimonate salts and characterized by use of a combination of NMR, IR and UV-vis spectroscopic methods and by mass spectrometry.

Terminal Phosphido Complexes of the Ru(n5-Cp?) Fragment

In situ generation of the five-coordinate complex Ru(n5-Cp?)(PR2)(PPh3) (2), via dehydrohalogenation of Ru(n5-Cp?)Cl(PR2H)(PPh3), has allowed its reactivity toward a range of small molecules to be compared with that of its well-studied analogue Ru(n5-indenyl)(PR2)(PPh3) (1), in a study designed to assess the likelihood of variable hapticity in the chemistry of complex 1. Reactions of 2 with hydrogen, carbon monoxide, phenylacetylene, ethylene, acrylonitrile, and 1-hexene demonstrate enhanced nucleophilicity/basicity of the terminal phosphido ligand in 2 relative to that in complex 1. Complex 2 also exhibits greater lability of the PPh3 ligand, leading to substitutional product mixtures that were not observed for 1. Both of these features are consistent with the more electron-rich and sterically imposing nature of the Cp? ligand in 2 relative to the indenyl ligand in 1. Nevertheless, the fundamental transformations of the phosphido ligand are comparable for the two complexes. This suggests that variable hapticity does not play a role in reactions of indenyl complex 1, since n5-n3 shifts are unlikely to occur for Cp? complex 2. The implications of these reactivity studies for the design of highly active, yet stable, ruthenium half-sandwich catalysts for hydrophosphination are discussed.
