Ruthenium Complexes of 2,2?-Bipyridine-6,6?-diphosphonate Ligands for Water Oxidation

Two novel ruthenium complexes, [Ru(2,2?-bipyridine-6,6?-diphosphonato)(pic)2] (2) (pic=4-picoline) and [Ru(6,6?-diisopropyl-2,2?-bipyridine-6,6?-diphosphonato)(pic)2] (3) bearing phosphonate groups have been synthesized and characterized by NMR spectroscopy, elemental analyses, X-ray crystallography, cyclic voltammetry, and UV/Vis spectroscopy. Both complexes show catalytic water oxidation activity by electrochemistry. At pH 7, the RuII/III redox couple of 2 is observed at a lower potential than that of 3, yet significantly, 3 oxidizes water at a lower onset potential. At pH 1 however, 2 and 3 have comparable catalytic reactivity using sacrificial oxidant CeIV. We propose that water oxidation activities of 2 and 3 are influenced by overall charges. For example, in oxidizing from RuII to RuIII at pH 7, 2 acquires a ?1 overall charge whereas 3 acquires a +1 charge. Charge-dictated electrostatic effects may govern binding of a water molecule to the metal site.

Kinetics and Mechanism of Ruthenium(III) Catalysed Oxidation of Benzylamine by Hexacyanoferrate(III) in Alkaline Medium

The kinetics of ruthenium(III) catalysed oxidation of benzylamine by potassium hexacyanoferrate(III) in alkaline medium has been carried out.The reaction has been observed to be zero order with respect to oxidant and first order to lower concentrations of substrate and alkali tending towards zero order at their higher concentrations.Further, with respect to ruthenium(III), the order has been observed to be unity.A probable mechanism explaining all the observed results has been postulated.The activation parameters have been calculated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Related Products of 10049-08-8

Binding of 9-Methylguanine to [cis-Ru(2,2?-bpy)2] 2+: First X-ray Structure of a cis-Bis Purine Complex of Ruthenium

Reaction of [cis-Ru(2,2?-bpy)2(O3SCF 3)2] (1) with 9-methylguanine (9-MeG) affords the cis-[Ru(2,2?-bpy)2(9-MeG)2]2+ complex (2) in good yield. Two bases bind to the metal center via the N7 atoms. X-ray structure analysis of 2(SO3CF3)2 (monoclinic, P21/n, a = 12.5159(6) A, b = 20.0904(13) A, c = 17.1202(9) A, beta = 98.981(6), V= 4252.1(4) A3, Z = 4) reveals that the two bases are in a head-to-tail (HT) orientation with base-base dihedral angle of 60.4. NMR studies confirm that the complex is stable in water for hours, and no evidence for guanine substitution by solvent molecules was found.

KINETICS AND MECHANISM OF RUTHENIUM(III)-CATALYSED OXIDATION OF ALLYL ALCOHOL BY MOLECULAR OXYGEN.

Oxidation of allyl alcohol by molecular oxygen catalysed by ruthenium(III) chloride in the pH range 1. 0 – 3. 0 is reported. The kinetics of the reaction, in the pH range 1. 0 – 2. 0, indicate a first-order dependence on ruthenium(III) ion and allyl alcohol concentrations and a zero-order dependence with respect to molecular oxygen concentration. The rate of oxidation was also found to be directly proportional to the hydrogen ion concentration. In the pH range 2. 0 – 3. 0, the rate of oxidation of allyl alcohol was found to be first order with respect to ruthenium(III) ion, first order with respect to allyl alcohol, and inversely proportional to hydrogen ion concentration.

A combined density functional and molecular mechanics approach (QM/MM) has been validated in a study of the substitution reactions: (i) (PH3)2Fe(CO)3 + 2ER3 mutually implies (ER3)2Fe(CO)3 + 2PH3 (ER3 = PMe3, PEt3, PMePh2, PPh3, PCyPh2, P(i)Pr3, PBz3, PCy3, AsEt3, AsPh3); and (ii) Cp’Ru(PH3)2Cl + 2ER3 mutually implies Cp’Ru(ER3)2Cl + 2PH3 (Cp’ = C5H5, C5(CH3)5; ER3 = PMe3, PEt3 P(n)Bu3, PMe2Ph, PMePh2, PPh3, AsEt3, P(OMe)3, P(OPh)3, P(OCH2)3CEt). The steric influence of the R substituents on the substitution enthalpies correlates well with experimental data. The combined QM/MM approach is also able to afford molecular structures in good accord with experimental estimates.

Synthesis and transition metal complexes of 1,1?-bis(diphenylethynylphosphino)ferrocene

The new ferrocene based bisphosphine [Fe{C5H4P(C[tbnd]CPh)2}2] (1) was synthesized in 82% yield by the treatment of bis(dichlorophosphino)ferrocene [Fe(C5H4PCl2)2] with four equivalents of lithium phenylacetylide. The reactions of 1 with aq. H2O2, elemental sulfur or selenium afforded bis(chalcogenide) derivatives, [Fe{C5H4P(E)(C[tbnd]CPh)2}2] (2 E = O, 3 E = S, 4 E = Se). The reaction of 1 with [M(NC5H11)2(CO)4] (M = Mo, W), [RuCp(PPh3)2Cl] and [M(COD)Cl2] (M = Pd, Pt) resulted in the formation of the respective chelate complexes, [Fe{C5H4P(C[tbnd]CPh)2}2{M(CO)4}] (5 M = Mo, 6 M = W), [Fe{C5H4P(C[tbnd]CPh)2}2{RuCp(Cl)}] (8) and [Fe{C5H4P(C[tbnd]CPh)2}2{MCl2}] (9 M = Pd, 10 M = Pt), whereas the reaction of 1 with [Ru(eta6-p-cymene)Cl2]2 and [AuCl(SMe2)] yielded the corresponding bimetallic complexes [Fe{C5H4P(C[tbnd]CPh)2}2{RuCl2(eta6-p-cymene)}2] (7) and [Fe{C5H4P(C[tbnd]CPh)2}2{AuCl}2] (15). The reactions between 1 and CuX in equimolar ratios also yielded binuclear complexes, [Fe{C5H4P(C[tbnd]CPh)2}2{CuX}2] (11 X = Cl, 12 X = Br, 13 X = I), whereas [Cu(CH3CN)4]BF4 yielded the cationic complex [(Fe{C5H4P(C[tbnd]CPh)2}2)2Cu]BF4 (14). All the compounds were characterized by spectroscopic methods and the structures of complexes 1, 5, 6, 8, 10, 13 and 14 were confirmed by single crystal X-ray diffraction studies.

Stereoselective synthesis of dienyl phosphonates via extended tethered ring-closing metathesis

Allylphosphonates of allylic alcohols were converted to conjugated dienyl phosphonates in a one-flask reaction, comprising a ring-closing metathesis (RCM), a base-induced ring-opening, and an alkylation. The ring-opening proceeds with very high diastereoselectivity, giving exclusively the (1Z,3E)-configured dienes. Single diastereomers and mixtures of diastereomers can be used as starting materials without noticeable effect on the diastereoselectivity of the sequence.

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.Product Details of 246047-72-3, you can also check out more blogs about246047-72-3

Total synthesis of the aspercyclides

Two different approaches to the eleven-membered biaryl ether lactones of the aspercyclide family are disclosed. The core regions of these highly strained targets, which are able to interfere with the binding of immunoglobulinE to its high affinity receptor, can either be forged by ring-closing olefin metathesis (RCM) or by a highly diastereoselective chromium-mediated Nozaki-Hiyama-Kishi (NHK) reaction. Whereas the RCM approach turned out to be responsive to minor changes in the substitution pattern of the substrate, the NHK route is more generally applicable. The preparation of the required cyclization precursor 43 hinged on a palladium-catalyzed orthoiodination reaction of 2-methylbenzoic acid, an efficient copper-catalyzed Ullmann coupling, and a Takai-Utimoto olefination as the key steps. Moreover, the esterification of the 2,6-disubstituted benzoic acid 34 with the sterically hindered secondary alcohol 37 was far from trivial. However, this and related transformations were accomplished by recourse to the corresponding acid fluorides, which provided excellent yields in cases in which the more commonly used acid chlorides or mixed anhydrides failed to afford any of the desiredproducts.
