The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.53152-69-5, Name is (1R,2R)-N1,N1,N2,N2-Tetramethylcyclohexane-1,2-diamine, molecular formula is C10H22N2. In a Article,once mentioned of 53152-69-5, Quality Control of: (1R,2R)-N1,N1,N2,N2-Tetramethylcyclohexane-1,2-diamine
When n-hexane solutions of an excess of sodium bis(trimethylsilyl)amide (NaHMDS) are combined with cesium halide (halide = Cl, Br, or I) in the presence of the tetradentate donor molecule [tris[2-(dimethylamino)ethyl]amine] (Me6TREN), the isolation and characterization of a series of sodium amide/sodium halide mixed aggregates was forthcoming. Cesium halide was employed because it efficiently reacted with NaHMDS to produce a molecular, soluble source of sodium halide salt (which was subsequently captured by an excess of NaHMDS) via a methathetical reaction. These mixed sodium amide/sodium halide complexes are formally sodium sodiates, are deficient in halide with respect to the amide, and have the general formula [{Na5(mu-HMDS)5(mu5-X)}{Na(Me6TREN)}] [where X = Cl (1), Br (2), or I (3)]. The influence of the donor ligand was studied for the NaI/NaHMDS system, and when n-hexane solutions of this composition were treated with tridentate donors such as N,N,N?,?,?-pentamethyldiethylenetriamine (PMDETA) or N,N,N?,N?-tetramethyldiaminoethyl ether (TMDAE), solvent-separated ion-pair cocomplexes [Na5(mu-HMDS)5(mu5-I)]'[Na3(mu-HMDS)2(PMDETA)2]+ (4) and [Na5(mu-HMDS)5(mu5-I)]'[Na(TMDAE)2]+ (5) were isolated. However, upon reaction with bidentate proligands such as the chiral diamine (R,R)-N,N,N?,N?-tetramethylcyclohexane-1,2-diamine [(R,R)-TMCDA] or N,N,N?,N?-tetramethylethylenediamine (TMEDA), neutral complexes [Na4(mu-HMDS)3(mu4-I)(donor)2] [donor = (R,R)-TMCDA (6) and TMEDA (7)] were produced. To illustrate the generality of the latter reaction with other halides, [Na4(mu-HMDS)3(mu4-Br)(TMEDA)2] (8) was also prepared by employing NaBr in the synthesis instead of NaI.
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.Quality Control of: (1R,2R)-N1,N1,N2,N2-Tetramethylcyclohexane-1,2-diamine, you can also check out more blogs about53152-69-5
