Recommanded Product: 10343-06-3. In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. Introducing a new discovery about 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose

Gluco- and ribosylation of the bases of sugar protected inosine and uridine were investigated, obtaining only adducts with beta-configuration at the new glycosidic carbon; stereospecific insertion of a sugar moiety at the 1-N of inosine was achieved either using a Mitsunobu approach (for ribosylation) or by direct coupling of 1-alpha-bromoglucose 13 with 2′,3′,5′-tri-O-acetylinosine for glucosylation. 1-(beta-D-glucosyl)-inosine, chosen as starting substrate for glucosylated analogs of cyclic IDP-ribose, was phosphorylated at the primary hydroxyls and tested in intramolecular pyrophosphate bond formation.

The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis . 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, Computed Properties of C12H22O11

The ligands {[bis(2-pyridyl)amino]carbonyl}ferrocene (L1) and 1,1?-bis{[bis(2-pyridyl)amino]carbonyl}ferrocene (L2) have been prepared by treatment of the mono- or 1,1?-bis(chlorocarbonyl)ferrocene derivatives with dipyridylamine in a 1:1 or 1:2 ratio, respectively. The ligand properties of these compounds towards group 11 and palladium complexes have been studied. Ligand L1 coordinates to these compounds to give four-coordinate [Cu(L1) 2]+, [PdCl2(L1)] and [Ag(OTf)(L1)(PR 3)] or three-coordinate [Ag(OTf)(L1)] and [Au(C6F 5)(L1)] compounds. The ligand coordinates in a chelate fashion in all cases. The reactivity of L2 is somewhat different because coordination to copper or silver atoms can take place through several pyridine units either from different cyclopentadienido rings, as in [Cu(L2)]+, [Ag 2(OTf)2-(L2)] and [Ag(OTf)(L2)(PPh3)], or from the same cyclopentadienido ring, as in [Ag2(OTf)2(L2) (PPh3)2]. Coordination as a bridging ligand for four gold atoms has also been achieved in [Au4(C6F5) 4(L2)] and [Au4(L2)(PPh3)4](OTf) 4. The ligands and some complexes have been characterized by X-ray diffraction studies and show the presence of several hydrogen bonds that lead to supramolecular structures. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

The crystal structures of *H2O (1) and *H2O (2) where bipyam-H = bis(2-pyridyl)amide, have been determined by X-ray analysis, in the orthorhombic space group Pnn2: (1), a=14.092(3), b=12.895(3), c=11.190(2) Angstroem, Z=2, and R=0.032 for 2453 observed and 2029 unique reflections; (2), a=14.186(3), b=13.040(3), c=11.313(2) Angstroem, Z=2, and R=0.043 for 1574 observed and 1465 unique reflections.The two structures are isomorphous with near isostructural units in special positions of two-fold symmetry and a non-co-ordinated water molecule.The Cu3N12X2 chromophores involve nearly linear Cu3 units, Cu-Cu-Cu 178.4 deg (mean), terminated by the two halide anions.The four separate bipyam-H ligands act as tridentate ligands, involving co-ordination to the three separate copper(II) ions, with Cu-Cu distances of 2.471(1) and 2.468(1) Angstroem, for (1) and (2), respectively.If the Cu-Cu separations are ignored, the central Cu atom in both structures involves a four-co-ordinate rhombic coplanar CuN4 chromophore generated by the central amido nitrogens of the four bipyam-H ligands.The two terminal Cu atoms involve a square-based pyramidal CuN4X chromophore, generated by the terminal pyridine nitrogens of the four bipyam-H ligands and an axial halide anion.An average dihedral angle of 48 deg is involved between the planes of the pyridine rings of the individual bipyam-H ligands, which results in a spiral configuration of the units.The spin-only magnetic moment of the complex (1) is ca. 1.40 B.M. per Cu atom, consistent with antiferromagnetic coupling between the copper(II) atoms of the trimer.Both complexes are e.s.r. silent, again consisitent with strong antiferromagnetic coupling.The electronic spectra of (1) and (2) have a band maximum at 15500 cm-1, with a high-energy shoulder at 19230 cm-1, consistent with the two different stereochemistries present.
