A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 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.

Dimolybdenum complexes of bis(2-pyridyl)amine (Hdpa) ligand and its anion (dpa-); Transformation of chelating eta2-Hdpa to bridging eta2-dpa-
The reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with 1 equiv. of Hdpa (Hdpa=bis(2-pyridyl)amine) in CH2Cl2 afforded the complex cis-Mo2(O2CCR3)2X 2(eta2-Hdpa) (R=H, X=Cl, 1; R=H, X=Br, 2; R=F, X=Cl, 3, R=F, X=Br, 4). Layering of a Mo2(O2CCF3)4 solution in CH2Cl2 with Hdpa in ether produced red and yellow crystals, which were characterized as Mo2(eta2-dpa)4 (5), and Mo2(O2CCF3)4(eta 1-HO2CCF3)2 ¡¤ 2Hdpa (6), respectively. Complex 5 can also be prepared by reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with excess Hdpa. Their UV-Vis and IR spectra have been recorded and the structures of 4, 5 and 6 have been determined. The Hdpa ligand in 4 is coordinated to the metal centers via two terminal pyridine nitrogen atoms with a cis-N conformation. The dpa- ligands in 5 are bridged to the metal centers via one terminal nitrogen atom and the central nitrogen atom. The aligned-N conformation of the dpa- ligand is stabilized by both the intramolecular MoN and C-HN interactions. In 6, the CF3COOH ligands coordinate to the metal centers in the axial positions with eta1-bonding modes and the Hdpa molecules adapt cis-N conformations.
