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, Formula: C12H22O11
Effects of metal ions and ligands on transesterification: Synthesis, structures, and catalytic activities of a series of cation-anionic complexes with dipyridylamine ligands
A series of cation-anion complexes derived by 2,2?-dipyridylamine (Hdpa) and carboxylate ligands with formulas [Ni(Hdpa)2(CH 3COO)]Cl(CH3OH) (1), [Co(Hdpa)2(CH 3COO)]Cl(CH3OH) (2), [Ni(Hdpa)2(CH 3CH2CH2COO)]Cl (3), [Co(Hdpa) 2(CH3CH2CH2COO)]Cl (4), [Ni(Hdpa)2(C6H5COO)]Cl (5), and [Co(Hdpa) 2(C6H5COO)]Cl (6), were synthesized and characterized by IR, elemental analysis, MS(ESI), TG analysis, UV-Vis, and fluorescence spectra. X-ray single crystal structural analysis showed that the coordination geometries of metal ions in these complexes are similar and they are cation-anion species. The hydrogen-bonding structures are 1-D chains through the N-H…Cl bonds. There are weak stacking interactions between pyridine rings in 1-4, while there are no stacking interactions in 5 and 6. We have investigated the transesterification of phenyl acetate with methanol catalyzed by 1-6 under mild conditions; 1-4 are homogeneous catalysts while 5 and 6 are heterogeneous catalysts due to their poor solubility in methanol. Cobalt complexes exhibit higher catalytic activities than corresponding nickel complexes. Complex 4 is the best catalyst of these six complexes.
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.Formula: C12H22O11, you can also check out more blogs about499-40-1
