The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Article，once mentioned of 4488-22-6, SDS of cas: 4488-22-6
Condensation and subsequent reduction of 2,2?-diaminobiphenyls 5 with 6?- and 5?-substituted 6-carbaldehyde-2,2?-bipyridines 4 yielded N,N?-bis(2,2?-bipyridine-6-ylmethyl)-2,2?-biphenyl- enediamines 7, which were employed as hexadendate ligands with N6 donor sets in the synthesis of dicationic [Fe2+(7-kappa6N)] complexes 8. Dependent on the substitution pattern the respective complexes are found in the HS state (8b and 8c) or show SCO behaviour. By means of temperature- dependent susceptibility measurements, usingEvans’ method, the thermodynamic parameters DeltaH, DeltaS and T1/2 for the SCO have been determined. T1/2 as well as DeltaH are remarkably susceptible to substitution next to the central C-C bond of the biphenyl bridge. A new series of ligands with an AB2 structure were synthesized and employed in Fe2+ SCO complexes. DeltaH, DeltaS and T1/2 for the SCO were determined using Evans’ method. The results clearly show a dependency of the spin state on the substitution pattern. The steric effects of substituents placed at the 6 and 6? positions in the biphenyl moiety are effectively transported through the biphenyl bridge. Copyright
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.SDS of cas: 4488-22-6, you can also check out more blogs about4488-22-6
