Ruthenium catalysts

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article，once mentioned of 32993-05-8, category: ruthenium-catalysts

RuCl(dppf)(eta-C5H5) was treated with NH4PF6 in acetonitrile to give the cationic complex PF6 in good yield, in which no bonding interaction between iron and ruthenium atoms was found.The reaction of RuCl(dppf)(eta-C5H5) with terminal acetylene in the presence of NH4PF6 gave the corresponding vinylidene complexes, which were converted on treatment with base or alumina to the corresponding acetylide complexes.A similar reaction with methyl propiolate at room temperature gave the corresponding vinyl ether complex rather than the acetylide complex as a main product, and a novel degradation reaction to the cationic carbonyl complex was also observed.

The new complexes [(eta6-arene)RuCl(C5H4N-2-CH=N-R)]PF6 (arene = C6H6 with R = 4- flourophenyl (1), 4-chlorophenyl (2), 4-bromophenyl (3), 4 -iodophenyl (4), 2, 5-dichlorophenyl (5) or p-cymene with R = 4-flourophenyl (6), 4-chlorophenyl (7), 4-bromophenyl (8), 4- iodophenyl (9), 2, 5 – dichlorophenyl (10)) have been synthesized by reacting the ruthenium arene precursors [(eta6-arene)Ru(mu-Cl)Cl]2, with the N,N?-bidentate ligands in a 1:2 ratio. Full characterization of all complexes was accomplished using 1H and 13C NMR, elemental analyses, UV-Vis spectroscopy, thermal analysis, IR spectroscopy and single crystal x-ray structures for compounds 7 and 10. The single crystal structures confirmed coordination of the ligand to the ruthenium(II) centre. The Ru(II) centre has a pseudo-octahedral three legged piano stool geometry in which the arene ring occupies the apex of the stool and the ruthenium is coordinated to the N,N?-bidentate ligand and a chloride ligand at the base of the stool. Two polymorphs of 7 were identified. The synthesized Ru(II) complexes were tested as catalysts for the oxidation of styrene to benzaldehyde using NaIO4 as a co-oxidant. All complexes were active catalysts for styrene oxidation and they gave high yields of benzaldehyde as the major product.

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, category: ruthenium-catalysts

An NAD/NADH-functionalized ligand, benzo[b]pyrido[3,2-f][1,7]-phenanthroline (bpp), was newly synthesized. A Ru compound containing the bpp ligand, [Ru(bpp)(bpy)2]2+, underwent 2e- and 2H+ reduction, generating the NADH form of the compound, [Ru(bppHH)(bpy)2]2+, in response to visible light irradiation in CH3CN/TEA/H2O (8/1/1). The UV-vis and fluorescent spectra of both [Ru(bpp)(bpy)2]2+ and [Ru(bppHH)(bpy)2]2+ resembled the spectra of [Ru(bpy)3]2+. Both complexes exhibited strong emission, with quantum yields of 0.086 and 0.031, respectively; values that are much higher than those obtained from the NAD/NADH-functionalized complexes [Ru(pbn)(bpy)2]2+ and [Ru(pbnHH)(bpy)2]2+ (pbn = (2-(2-pyridyl)benzo[b]-1.5-naphthyridine, pbnHH = hydrogenated form of pbn). The reduction potential of the bpp ligand in [Ru(bpp)(bpy)2]2+ (-1.28 V vs SCE) is much more negative than that of the pbn ligand in [Ru(pbn)(bpy)2]2+ (-0.74 V), although the oxidation potentials of bppHH and pbnHH are essentially equal (0.95 V). These results indicate that the electrochemical oxidation of the dihydropyridine moiety in the NADH-type ligand was independent of the pi system, including the Ru polypyridyl framework. [Ru(bppHH)(bpy)2]2+ allowed the photoreduction of oxygen, generating H2O2 in 92% yield based on [Ru(bppHH)(bpy)2]2+. H2O2 production took place via singlet oxygen generated by the energy transfer from excited [Ru(bppHH)(bpy)2]2+ to triplet oxygen.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, COA of Formula: C31H38Cl2N2ORu.

Reactions of the Grubbs 3rd generation complexes [RuCl2(NHC) (Ind)(Py)] (N-heterocyclic carbene (NHC)=1,3-bis(2,4,6- trimethylphenylimidazolin)-2-ylidene (SIMes), 1,3-bis(2,6- diisopropylphenylimidazolin)-2-ylidene (SIPr), or 1,3-bis(2,6- diisopropylphenylimidazol)-2-ylidene (IPr); Ind=3-phenylindenylid-1-ene, Py=pyridine) with 2-ethenyl-N-alkylaniline (alkyl=Me, Et) result in the formation of the new N-Grubbs-Hoveyda-type complexes 5 (NHC=SIMes, alkyl=Me), 6 (SIMes, Et), 7 (IPr, Me), 8 (SIPr, Me), and 9 (SIPr, Et) with N-chelating benzylidene ligands in yields of 50-75 %. Compared to their respective, conventional, O-Grubbs-Hoveyda complexes, the new complexes are characterized by fast catalyst activation, which translates into fast and efficient ring-closing metathesis (RCM) reactivity. Catalyst loadings of 15-150 ppm (0.0015-0.015 mol %) are sufficient for the conversion of a wide range of diolefinic substrates into the respective RCM products after 15 min at 50 C in toluene; compounds 8 and 9 are the most catalytically active complexes. The use of complex 8 in RCM reactions enables the formation of N-protected 2,5-dihydropyrroles with turnover numbers (TONs) of up to 58 000 and turnover frequencies (TOFs) of up to 232 000 h-1; the use of the N-protected 1,2,3,6-tetrahydropyridines proceeds with TONs of up to 37 000 and TOFs of up to 147 000 h-1; and the use of the N-protected 2,3,6,7-tetrahydroazepines proceeds with TONs of up to 19 000 and TOFs of up to 76 000 h-1, with yields for these reactions ranging from 83-92 %. The tortoise and the hare: The use of diphenylalkylamino-based instead of phenyldialkylamino-based styrenes (see figure) leads to rapidly initiating precatalysts that enable very fast ring-closing metathesis reactions with turnover numbers of up to 58 000 and turnover frequencies of up to 232 000 h-1.
