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. In a Article，once mentioned of 499-40-1, COA of Formula: C12H22O11
Three new iridium (III) acetylacetonate complexes with an axial bipyridine ligand were synthesised via the direct reaction of [bis(acac-O,O’)(acac-C 3)Ir(H2O)] and the corresponding bipyridine, and their molecular structures were determined by using single-crystal X-ray diffraction. The bipyridine used was di-2-pyridylketone, 2,2′-bipyridine and 2,2′-bipyridylamine, respectively. The results revealed that only mononuclear iridium complexes were obtained, although bipyridine has two N coordinate atoms, probably due to the great steric hindrance existing around the coordinate sphere if two bis(acac-O,O’)(acac-C3)Ir units were bridged by bipyridine. All these complexes are coordinated in one axial direction by bipyridine as a mono-dentate ligand in a slightly distorted octahedral coordination geometry. Springer Science+Business Media B.V. 2012.
