The synthesis, characterization and single-crystal structure determination of chiral compounds (eta5-C5R5)Ru(PHPh2)(PPh3)Cl (R=H 3, R=Me 4) and prochiral Cp * Ru(PHPh2)2Cl (6) are described. Compound 6 has been available from reaction of PHPh2 and several starting materials. The X-ray structure comparison between 3, 4 and 6 allowed us to compare the influence of the phosphine, Cp and Cp * ligands in these half-sandwich compounds. In addition, a structural investigation was carried out on Cp * Ru(NBD)Cl (7).

A star is born: Star polymer catalysts that carry a versatile microgel-core reaction vessel were obtained from catalyst interchange, coupled with ruthenium-catalyzed living radical polymerization, in situ hydrogenation, and removal and introduction of metals (see picture). Thanks to the catalyst encapsulation in the unique environment, the star catalysts show high activity, versatility, functionality tolerance, and recyclability in living radical polymerization.

Application of 92361-49-4, An article , which mentions 92361-49-4, molecular formula is C46H45ClP2Ru. The compound – Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

All polymerization reactions are categorized into two large different families, chain- and step-growth polymerizations, which are typically incompatible. Here, we report the simultaneous chain- and step-growth polymerization via the metal-catalyzed radical copolymerization of conjugated vinyl monomers and designed monomers possessing unconjugated C – C and active C-Cl bonds. Especially, almost ideal linear random copolymers containing both vinyl polymer and polyester units in a single polymer chain were formed by the CuCl/1,1,4,7,10,10-hexamethyltriethylenetetramine- or RuCp*Cl(PPh 3)2-catalyzed copolymerization of methyl acrylate (MA) for the chain-growth polymerization and 3-butenyl 2-chloropropionate (1) for the step-growth polymerization. In contrast, other transition metal catalysts, such as CuCl with tris[2-(dimethylamino)ethyl]amine or N,N,N?,N?, N?-pentamethyldiethylenetriamine and FeCl2/PnBu3, resulted in branched structures via the concomitant chain-growth copolymerization of 1 with MA. The polymerization mechanism was studied in detail by NMR and MALDI-TOF-MS analyses of the polymerizations as well as the model reactions. Furthermore, a series of copolymers changing from random to multiblock polymer structures were obtained by varying the feed ratios of the two monomers. These copolymers can be easily degraded into lower molecular weight oligomers or polymers via methanolysis of the ester-linkages in the main chain using sodium carbonate.

A quite general approach for the preparation of eta5- and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl] 2 (arene = C6H6, C10H14 and C6Me6) and eta5- pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5- C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) reacts with two equivalents of the ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) in presence of NH 4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(L1)Cl]PF6 {arene = C6H6 (1), C10H14 (2) and C 6Me6 (3)}, [(eta6-arene)Ru(L 2)Cl]PF6 {arene = C6H6 (4), C 10H14 (5) and C6Me6 (6)}, and [(eta5-C5Me5)M(L1)Cl]PF 6 {M = Rh (7), Ir (8)} and [(eta5-C5Me 5)M(L2)Cl]PF6 {M = Rh (9), Ir (10)}. However the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3) 2Cl], [(eta5-C5H5)Os(PPh 3)2Br], [(eta5-C5Me 5)Ru(PPh3)2Cl] and [(eta5-C 9H7)Ru(PPh3)2Cl] complexes react in presence of one equivalent of ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) and one equivalent of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(L 1)]PF6 (11), [(eta5-C5H 5)Os(PPh3)(L1)]PF6 (12), [(eta5-C5Me5)Ru(PPh3)(L 1)]PF6 (13) and [(eta5-C9H 7)Ru(PPh3)(L1)]PF6 (14) and [(eta5-C5H5)Ru(PPh3)(L 2)]PF6 (15), [(eta5-C5H 5)Os(PPh3)(L2)]PF6 (16), [(eta5-C5Me5)Ru(PPh3)(L 2)]PF6 (17) and [(eta5-C9H 7)Ru(PPh3)(L2)]PF6 (18) respectively. These compounds have been systematically characterized by IR, NMR and mass spectrometry. The molecular structures of 2, 4 and 15 have been established by single crystal X-ray diffraction study and some of the representative complexes have also been studied by UV-visible spectroscopy. The crystal packing diagram of complex 4 reveals that the cation [(eta6-C6H6)Ru(L2)Cl]+ is engaged in non-covalent interaction. This compound gives rise to a 1D helical architecture along the ‘a’ axis via intermolecular NH?Cl hydrogen bonds.

A series of mononuclear indenyl and pentamethylcyclopentadienyl ruthenium(II) complexes of formulation [(eta5-L3) Ru(PPh3)(L2)]X, (where L3 = indenyl, pentamethylcyclopentadienyl; X = PF6 or BF4 and L 2 = azine ligands) have been prepared by the reaction of [(eta5-L3)Ru(PPh3)2(CH 3CN)]X with the appropriate azine ligands in methanol or dichloromethane/benzene mixture. The reaction of nitro substituted azine ligands with the complexes [(eta5-L3)Ru(PPh3) 2(CH3CN)]X are solvent dependent. All these complexes were isolated as their PF6 or BF4 salts. The complexes were fully characterized with the help of microanalyses, FT-IR and NMR spectroscopy. The molecular structure of representative complexes 5c and 6a were established by single X-ray crystallography.

N-heterocyclic carbene complexes of ruthenium(II), [CpRu(L*)2Cl] (2) and [CpRu(CO)(L*)-Cl] (3) (Cp = eta5-C5H5; L* = l,3-dicyclohexyl-imidazolin-2-ylidene), have been obtained in high yields by reaction of [CpRu(PR2R?)2Cl] (R = R? = Ph, la; R = Ph, R? = 2-MeC6H4, 1b) and [CpRu(CO){PPh2(2-MeC6H4)}Cl] (1c), respectively, with the free carbene L*. The mixed dicarbene complex [CpRu(=CPh2)(L*)Cl] (4) is prepared from [CpRu(=CPh2){PPh2(2-MeC6H4-Cl] (1d) and an equimolar amount of L*, whereas subsequent reaction of 1d with L* leads to formation of 2, along with tetraphenylethene. The reaction of [Cp*Ru(PPh3)2Cl] (1e) with L* gives the pentamethylcyclopentadienyl derivative [Cp*Ru(PPh3)(L*)Cl] (5) (Cp* = eta5-C5Me5) by displacement of 1 equiv of PPh3 Complex 5 reacts in toluene with CO, pyridine (Py), and N2CHCO2Et, affording [Cp*Ru(CO)(L*)Cl] (6), [Cp*Ru(Py)(L*)Cl] (7), and the mixed dicarbene [Cp*Ru(=CHCO2Et)(L*)Cl] (8), which were isolated in high yields. The molecular structure of complex 6 has been determined by an X-ray investigation, and the carbene-ruthenium distance clearly indicates a single bond (2.0951(18) A). The N-heterocyclic carbene does not undergo substitution by other two-electron ligands.

Pentamethylcyclopentadienyl ruthenium(II) complexes containing chiral diphosphines: Synthesis, characterisation and electrochemical behaviour. X-ray structure of (eta5-C5Me5)Ru{(S,S)-Ph 2PCH(CH3)CH(CH3)PPh;2}Cl

Some pentamethylcyclopentadienyl ruthenium(II) diphosphine chloride complexes have been prepared by ligand exchange starting with the parent triphenylphosphine derivatives and their reactivities compared with those of the corresponding cyclopentadienyl compounds. The pentamethyl ligand causes a greater extent of asymmetric induction when the (R)-prophos and (R)-phenphos ligands are used as well as a higher lability of the stereochemistry at the stereogenic ruthenium centre. A shift of about 200 mV in the oxidation potential is caused by the substitution at the penta-hapto ligand. The order of basicity of the diphosphine ligands was also evaluated and was found to be consistent with previous determinations. The crystal structure of (eta5-C5Me)Ru{(S,S)-chiraphos}C1 shows a coordination around the ruthenium atom similar to that found for the (eta5-C5H5)Ru{(S,S)-chiraphos}Cl complex.

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.
