The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, name: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal

The reactivities and the site-selectivities of the hydrolyses of ATP and UTP by the catalysts of the metal complexes of adenine-linked di-2-pyridylamine ligands, (Py)2N-(CH2)n-Ade (L: n = 3, 4, 5, and 6), were examined. It was found that these adenine-dipyridylamine coordinated Cu2+ complexes (with 2:1 ratios of [CuII(L)]2+ : ATP or [CuII(L)]2+ : UTP) were more reactive for the hydrolyses of ATP and UTP than the complexes of ligands containing other metal ions (Mg2+, Ni2+, and Zn2+) at 40C and pH 7.3 (HEPES buffer), as reflected in much higher product ratios of ADP/AMP and UDP/UMP than those of Cu2+ alone. The observed high reactivity and selectivity are interpreted in terms of the base-base stackings between an adenine moiety of ATP or an uracil moiety of UTP and an adenine of the ligands, and of the selective coordination of Cu2+ to oxide ions in phosphate residues in the ternary complexes of ligand-Cu2+-ATP. The Cu2+-complex of di-2-pyridylamine having no adenine moiety, which is the active center of [CuII(L)]2+, promoted the hydrolyses of ATP and UTP less efficiently than the aquacopper(II) ion. The number of spacer methylene groups of the ligands influenced the hydrolytic activity of the Cu2+-complexes of these adenine-dipyridylamine ligands. The complexes of [CuII(L-4)]2+ and [CuII(L-5)]2+ were the most reactive and site-selective for the hydrolyses of ATP and UTP, respectively.

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.name: (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, you can also check out more blogs about499-40-1

Three new triply-bridged dinuclear copper(II) compounds with carboxylato bridges, [Cu2(mu-O2CH)(mu-OH)(mu-Cl)(dpyam) 2](PF6) (1), [Cu2(mu-O2CH) 2(mu-OH)(dpyam)2](PF6) (2) and [Cu 2(mu-O2CCH2CH3) 2(mu-OH)(dpyam)2](ClO4) (3) (dpyam = di-2-pyridylamine) have been synthesized and characterized crystallographically and spectroscopically. Compound 1 consists of a dinuclear unit in which both copper(II) ions are bridged by three different ligands, i.e., formate, chloride and hydroxide anions, providing a distorted trigonal bipyramidal geometry with a CuN2O2Cl chromophore. Compounds 2 and 3 have two bridging formato ligands and two bridging propionato ligands, respectively, together with a hydroxo bridge. The carboxylato ligands in both compounds 2 and 3 exhibit different coordination modes. One is in a syn, syn eta1: eta1:mu2 bridging mode and the other is in a monoatomic bridging mode. The structure of compound 2 involves a dinuclear unit, with a distorted trigonal bipyramidal geometry around each Cu(II) ion with a CuN2O3 chromophore. Compound 3 contains a non-centrosymmetric unit; the coordination environment around Cu(1) is a distorted square-pyramidal geometry and an intermediate geometry of sp and tbp around the Cu(II) ion. The Cu?Cu separations are 3.061, 3.113 and 3.006 A? for compounds 1, 2 and 3, respectively. The EPR spectra of all three compounds show a broad isotropic signal with a g value around 2.10. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a moderate ferromagnetic interaction between the Cu(II) ions with a singlet-triplet energy gap (J) of 79.7, 47.8 and 24.1 cm-1, for compounds 1, 2 and 3, respectively. Also a very weak intermolecular antiferromagnetic interaction was observed between the dinuclear units.

Two new isostructural M(II) (M = Ni, Co) complexes with 2,2′-dipyridylamine (dipya) and dianion of terephthalic acid (H2tpht), [M(dipya)2(H2O)2](tpht) · 2H2O, have been synthesized by ligand exchange reaction and characterized by single-crystal X-ray diffraction, FTIR spectroscopy, TG/DSC analysis and magnetic measurements. The crystal structures of [M(dipya)2(H2O)2](tpht) · 2H2O consist of discrete complex units in which M(II) adopts deformed octahedral geometries. Two dipya ligands and two water molecules are coordinated to M(II) atom, tpht acts as a counter ion, while additional two water molecules remained uncoordinated. By numerous hydrogen bonds, all structural fragments are connected in three different chains which extend along [100], [010] and [001] directions, giving as a result a complex 3D network. The stabilization of 3D structure is accomplished by non-covalent face to face phi-phi interactions among pyridyl ring of dipya and benzene ring of tpht from adjacent chains. Towards the applied magnetic field, the both complexes exhibited almost perfect paramagnetic behavior.

A series of divalent nickel and copper complexes and a series of mixed-ligand nickel(II) chelates have been prepared and characterized. The general formula of the complexes is [cation]2[M(1,1-dithiolate) 2] (M = Ni(II), Cu(II)), and that of the mixed-ligand is [Ni(enR)(SS)], containing the dianion of 1,1-dithiolate derivatives and an N-alkyl- or N-phenyl-substituted 1,2-diaminoethane or a bidentate nitrogenous base, enR. The structures of the complexes, both in the solid state and in solution, have been determined by IR, UV-Vis, room temperature magnetic and electrical conductance measurements. The MS4 chromophoric group is common to all of the homoleptic complexes and contains two four-membered chelate rings. The MS2N2 chromophoric group is common to the mixed-ligand complexes. The 1,1-dithiolate derivatives are substituted isomaleonitriles of the formula Y(CN)CCS22-, where Y = CONH2 (1-cyano-1-carboamido-2,2-ethylenedithiolate, CCED); COOEt (1-cyano-1- carboethoxy-2,2-ethylenedithiolate, CED); ph (1-cyano-1-phenyl-2,2- ethylenedithiolato, CPD) and Cl-ph (1-cyano-1-chlorophenyl-2,2- ethylenedithiolate, CCPD). X-ray structural analyses were performed for three compounds. The tetrabutylammonium(1-cyano-1-chlorophenyl-2,2-ethylenedithiolato) copper(II) complex consists of three molecules per unit cell. The copper atom lies on a crystallographic center of symmetry which requires the CuS4 unit to be planar. The average Cu-S bond length is 2.204 A. In the unit cell of the complex [(2,2?-bipyridine)(1-cyano-1-phenyl-2,2- ethylenedithiolato)nickel(II)] there are six nickel atoms. In the immediate vicinity of each nickel atom exist two sulfur and, at a shorter distance, two nitrogen atoms. The molecules in the unit cell are arranged in pairs, each pair forming two weak intermolecular Ni?S bond interactions at a distance of 3.617 A. In the novel sulfur-rich ligand 5-amino-4-(4-chlorophenyl)-[1,2] dithiole-3-thione, three carbon atoms are linked with two sulfur atoms forming a five-membered ring. All observed intramolecular bond lengths in the sulfur ring indicate delocalization of the pi-electron system.

A document type is Article, introducing its new discovery.

The generation of solar fuels by means of a photosynthetic apparatus strongly relies on the development of an efficient water oxidation catalyst (WOC). Cerium ammonium nitrate (CAN) is the most commonly used sacrificial oxidant to explore the potentiality of WOCs. It is usually assumed that CAN has the unique role to oxidatively energize WOCs, making them capable to offer a low-energy reaction pathway to transform H2O to O2. Herein, we show that CAN might have a much more relevant and direct role in WO, mainly related to the capture and liberation of O-O-containing molecular moieties.

A new unique tetranuclear copper(II) complex doubly-bridged by thiocyanate anions [Cu4(mu1,3-NCS)6(dpyam) 4(O2CH)2(H2O)2 (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction methods and magnetic measurements. The “outer” Cu ions, with a CuN3O(S, O) chromophore, have an axially elongated octahedral geometry. The basal plane of these outer Cu(II) ions consist of 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.980(2) and 2.008(2) A?, one nitrogen atom of a bridging thiocyanate anion (Cu-N distance 1.961(3) A?) and an oxygen atom of a formate molecule (Cu-O distance 1.977(1) A?). The axial positions are occupied by an oxygen atom of a water molecule (Cu-O distance 2.518(1) A? and by a sulfur atom of a bridging thiocyanate anion at a semi-coordination distance of 3.048(1) A?. The “inner” Cu atoms, with a CuN4(S2) chromophore do also have an axially elongated octahedral geometry. The basal plane is formed by 2 nitrogen atoms of the dpyam ligand with Cu-N distances of 1.995(2) and 2.018(3) A? and two nitrogen atoms of two bridging thiocyanate anions (Cu-N distances 1.946(3), 1.976(3) A?). The axial positions are occupied by two sulfur atoms of two bridging thiocynate anions (Cu-S semi-coordinating distances are 2.875(1) and3.126(1) A?). Each Cu ion is bridged by two mu1,3-NCS anions (in an equatorial-axial bridging mode) forming in this way a zigzag tetranuclear unit. The magnetic susceptibility data of the compound have been investigated between 5 and 200 K. The compound shows a very weak antiferromagnetic interaction between the Cu ions, in agreement with the non-overlapping magnetic orbitals of each Cu ion.

Addition of di(2-pyridyl)amine (dpa) to a solution formed by reaction of [Ru(CO)2Cl2]n with NaOAc resulted in the precipitation of [Ru(OAc)(CO)2(dpa)]2, a complex containing a rare example of monodentate dpa coordination. X-ray crystallography revealed a dinuclear complex with a Ru-Ru bond, having two cis-carbonyls on each ruthenium trans to oxygen donors of two mu-acetate ligands and a monodentate dpa approximately colinear with the Ru-Ru bond. A variable temperature 1H NMR study of this complex indicated fluxional behaviour of the dpa ligand in solution at room temperature, with the spectrum at 243 K corresponding to that predicted from the solid state structure. Heating of [Ru(OAc)(CO)2(dpa)]2 in ethanol formed [Ru2(OAc)(CO)4(dpa)2]+, which was isolated as the acetate salt. The X-ray structure of this complex and the analogous benzoate bridged [Ru2(PhCO2)(CO) 4(dpa)]Cl confirmed the presence of a diruthenium(I) core with terminal chelating dpa ligands and bridged by one carboxylate and two carbonyl ligands.
