A general synthetic approach based on the hydrolysis of R?3Si-NR2 with organic compounds containing acidic protons, to construct thin films of donor ligands on inorganic oxide surfaces that are subsequently used to support a variety of organometallic complexes, is reported. The reaction of surface hydroxyl groups on silica, glass, quartz, and single-crystal silicon with SiCl4, followed by NEt2H, affords surface-anchored Si-NEt2 moieties which, upon simple acid-base hydrolysis with HO-(CH2)n-XR2 (n = 3, X = N, R = C2H5; n = 3, X = P, R = C6H5; n = 4, X = P, R = C2H5), HO-C6H4-XR2 (X = P, R = C6H5; X = N, R = C2H5), and HO-CH(CH3)-(CH2)3-N(C2H 5)2 at ambient temperature, yield thin films containing terminal phosphine and amine donor ligands. These ligands are then used to covalently anchor organometallic complexes of Ni(0), Rh(I), Ru(II), and Pd(0) via bridge-splitting or ligand-displacement reactions. The synthesis of solution models to the surface-bound species and the characterization of the latter using numerous surface analytical techniques have proven useful in determining the conditions for the deposition process and in the evaluation of the structure of the supported metal complexes. A thin film of [Si]-O-(CH2)3PPh2Ni-(CO)2PPh 3 on glass catalyzes the oligomerization of phenylacetylene resulting in a product distribution different from that of a similar reaction in solution. The enhanced activity and selectivity of the organometallic Ni(0) thin films suggests that a positive role is played by the orientation of the surface-bound organometallic species in catalysis.

Application of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

We report our third and final investigation into the use of ruthenium based compounds for catalyzing the hydrosilylation of methylvinyldimethoxysilane with methyldimethoxysilane. The catalytic mechanism of dichloro (p-cymene) ruthenium (ii) (B1) is examined and compared to that of previously studied, less active catalysts. Density functional theory (DFT) has been applied to explore the possibility of fine-tuning the catalytic ability of B1.The eta 6-ligand and the sigma-donor ligands were varied to assess the steric and electronic factors that affect the reactivity of the catalyst. The catalytic ability is diminished by increasing the size of the eta 6-ligand (p-cymene replaced by 1,3,5-cyclooctatriene) or the sigma-donor strength of the other ligands (chloride replaced by methyl). The original catalyst (B1) appears to strike an optimum balance with regard to the sigma-donor capabilities of the ligands as it is able to interconvert relatively freely between the Ru(ii) and Ru(iv) oxidation states. All catalytically active compounds benefit from an initial exchange of one of the sigma-donor ligands for a hydride ligand in the induction step. The Royal Society of Chemistry 2009.

Systems of the type [(p-cym)Ru(PR3)(H)(H2BN iPr2)]+ (R = Cy, Ph) can be synthesized from (p-cym)Ru(PR3)Cl2 and H2BNiPr 2/Na[BArf4] and are best formulated as (hydrido)ruthenium kappa1-aminoborane complexes. VT-NMR measurements have been used to probe the sigma-bond metathesis process leading to Ru-H/H-B exchange, yielding an activation barrier of DeltaG ? = 7.5 kcal mol-1 at 161 K. Moreover, in contrast to the case for related non-hydride-containing systems, reactivity toward alkenes constitutes a viable route to a metal borylene complex via sacrificial hydrogenation.

The interionic structure of complexes [Ru(eta6-Arene){(2-R- C6H4)N=C(Me)-C(Me)=N(2-R-C6H4)}-Cl] X was investigated by an integrated experimental (PGSE diffusion and NOE NMR spectroscopy and X-ray single-crystal studies) and theoretical (DFT and ONIOM calculations) approach. PGSE NMR experiments indicated that ion pairing is the main aggregative process in CD2Cl2 and solvents with higher relative permittivity. They also showed that the tendency to ion pairing for isodielectric solvents is higher when the latter are protic. NOE interionic contacts were observed in 2-propanol-d8 even for BARF- salts. Ion pairing was favored by more coordinating counterions and an increase in concentration. An equilibrium between ion pairs and ion quadruples was observed by PGSE measurements in chloroform-d and benzene-d6. Such equilibrium is shifted toward ion quadruples by an increase in the concentration or when least coordinating counterions are used. For small fluorinated counterions, NOE studies located the anion in ion pairs above the plane containing the C=N imine moieties. ONIOM calculations found that this anion-cation orientation was at least 35.9 kJ/mol lower in energy than a second orientation with the anion close to cymene, which, in some cases, was observed in the solid state. NOE investigations on complexes with BPh4 – counterion did not allow a single orientation capable of explaining the observed NOEs to be found. X-ray studies showed that one cation is surrounded by two anions. ONIOM calculations found that these two anion-cation orientations have similar energies. X-ray and NOE NMR data strongly suggest that ion quadruples with BPh4- anions are constituted by an alternation of cations and anions. Interionic NOE intensities are almost invariant on passing from ion pairs to ion quadruples with small fluorinated counterions. X-ray studies suggested at least four possible structures of ion quadruples differing in both disposition and orientation of the ionic moieties. Three structures considered by ONIOM calculations were similar in energy, but more stable than the separated ion pairs.

Studies examining the photochemical reactivity of CpRu(PPh 3)2Cl and CpRu(PPh3)2Me towards the two electron donor ligands PEt3, C2H4, DMSO, the CH bond activatable reagents tetrahydrofuran, toluene, and pyridine, and the SiH bond activatable reagents HSiEt3 and HSi(Me) 2CHCH2) are presented. Broadband UV irradiation of CpRu(PPh3)2Cl leads to the formation of mono-substitution products such as CpRu(PPh3)(PEt3)Cl which are inert to further photochemical reaction, although thermally bis-substituted products such as CpRu(PEt3)2Cl can be formed. Room temperature irradiation of the related complex CpRu(PPh3)2Me with L = PEt3, C2H4, and DMSO also produces CpRu(PPh3)(L)Me. However, when these reactions are followed by in situ laser irradiation (325 nm source) at low temperature, three solvent activated isomers (ortho, meta and para) of CpRu(PPh3) 2(C6H4Me) are detected in toluene in addition to eta1- and eta3-coordinated benzyl species. Furthermore, photolysis in THF leads to both the C-D bond activation product CpRu(PPh3)2(OC4D7) and the labile coordination complex CpRu(PPh3)(THF)Me. Now CH4 rather than CH3D is liberated which suggests the involvement of an orthometallated species. The photochemically driven reaction of CpRu(PPh 3)2Me with HSiEt3 at 198 K generates CpRu(kappa2-2-C6H4PPh2)(SiEt 3)H and thereby confirms a role for an orthometallated complex is this process. Irradiation in cyclohexane produces the known orthometallated complex, CpRu(kappa2-2-C6H4PPh 2)(PPh3), and CH4 in accordance with this reactivity. The Royal Society of Chemistry 2014.

A unified step-economical strategy for accessing histone deacetylase inhibitory peptides is proposed, based on the late-stage installation of multiple zinc-binding functionalities via the cleavage of the strained cyclopropane ring in the common pluripotent cyclopropanol precursor. The efficacy of the proposed diversity-oriented approach has been validated by short stereoselective synthesis of natural product chlamydocin, containing a challenging-to-install fragment of (2S,9S)-2-amino-8-oxo-9,10-epoxydecanoic acid (Aoe) and a range of its analogues, derivatives of 2-amino-8-oxodecanoic and 2-aminosuberic acids.

The construction of fluorocarbene ligands within the coordination sphere of transition metal complexes using sequential nucleophilic and electrophilic addition to a vinylidene complex is described. Reaction of [Ru(eta5-C5H5)(dppe)(CCPhF)][N(SO2Ph)2] with [NMe4]F results in nucleophilic attack of fluoride at the metal-bound carbon of the vinylidene ligand to give alkenyl complex [Ru(eta5-C5H5)(dppe)(-CFCFPh)]. Subsequent eletrophilic fluorination with N-fluorobenzenesulfonimide (NFSI) results in the formation of the fluorinated carbene complex [Ru(eta5-C5H5)(dppe)(CF-CHFPh)][N(SO2Ph)2]. The fluorocarbene complexes undergo rearrangement to liberate free fluorinated alkenes, a process governed by the choice of solvent and anion, representing a new metal-mediated route to fluorinated alkenes from alkynes.

A formal intramolecular olefin metathesis process between the C=C double bond of a vinylidene ligand and a pendant vinyl group in several ruthenium complexes, each with a ferrocenyl group, is followed by an additional intramolecular C-C bond formation between a Cp ligand of the ferrocenyl substituent and the vinylidene ligand. The regioselectivity of the C-C bond formation reaction at either the substituted or the nonsubstituted Cp group of the ferrocenyl group is possibly influenced by a steric effect between the neighboring substituent near the ferrocenyl group and the phosphine ligand on the ruthenium metal center. The structure of one ruthenium complex resulting from such a C-C bond formation has been fully characterized by a single-crystal X-ray diffraction analysis.
