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
Metal-metal versus metal-ligand bonding in dimetal compounds with tridentate ligands
Reaction of a ‘VCl2·nTHF’ solution, prepared by the reduction of VCl3(THF)3 with NaBEt3H in THF, and Lidpa (dpa = the anion of 2,2′-dipyridylamine) in a mixture of THF/toluene at reflux temperature yields the bioctahedral V2(dpa)4·THF (1) compound. A similar reaction performed in THF at 0C gave [V2(dpa)3(mu-Cl)2Li2(THF)6][BEt3H] (2), in which a dpa ligand adopts a novel ‘doubly-chelating/bridging’ coordination mode. Compound 2 reacts with CH2Cl2 giving V2(dpa)3Cl2·2CH2Cl2 (3), a valence delocalized V(II)···V(6III) bioctahedral complex. In all three complexes, the formation of four additional metal-ligand bonds is favored over the formation of a V-V bond. The V···V separations are 3.038(2), 3.024(2) and 3.091(2) A? for 1-3, respectively. Crystal data are: compound 1, space group P2/n a = 13.102(2), b = 9.294(2), c = 16.510(4) A?, beta = 98.98(2), V = 1985.7(6) A?3 and Z = 2; compound 2, space group I2/a, a = 19.4674(8), b = 14.390(1), c = 24.219(2) A?, beta = 92.954(7), V = 6775.4(7) A?3 and Z = 2; compound 3, space group P21/c, a = 12.0853(8), b = 18.679(2), c = 16.709(2), beta = 109.98(1), V = 3544.9(6) A?3 and Z = 4.

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
