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.

Several Lewis base adducts of the synthetically important lithium tris(n-butyl)magnesiate LiMg(nBu)3 have been prepared and structurally characterised. The complexes were prepared by a co-complexation approach i.e., by combining the monometallic nBuLi and nBu2Mg reagents in hydrocarbon solution before adding a molar equivalent of a donor molecule (a bidentate amine, tridentate amine or cyclic ether). The lithium magnesiates all adopt variants of the “Weiss motif” structure, i.e., contacted ion pair dimers with a linear arrangement and metals connected by butyl anions, where tetrahedral magnesium ions are in the central positions and the lithiums occupy the outer region, solvated by a neutral Lewis donor [(donor)Li(mu-nBu)2Mg(mu-nBu)2Mg(mu-nBu)2Li(donor)]. When TMPDA, PMDETA or (R,R)-TMCDA [TMPDA = N,N,N?N?-tetramethylpropanediamine; PMDETA = N,N,N?,N?,N?-pentamethyldiethylenetriamine; and (R,R)-TMCDA = (R,R)-N,N,N?,N?-tetramethylcyclohexane-1,2-diamine], are employed, dimeric tetranuclear lithium magnesiates are produced. Due to the tridentate nature of the ligand, the PMDETA-containing structure (2) has an unusual ‘open’-motif. When TMEDA (TMEDA = N,N,N?,N?-tetramethylethylenediamine) is employed, a n-butoxide-containing complex [(TMEDA)Li(mu-nBu)(mu-OnBu)Mg2(nBu)2(mu-nBu)(mu-OnBu)Li(donor)] has been serendipitously prepared and adopts a ladder conformation which is commonly observed in lithium amide chemistry. This complex has also been prepared using a rational methodology. When 1,4-dioxane is employed, the donor stitches together a polymeric array of tetranuclear dimeric units (6). The hydrocarbon solution structures of the compounds have been characterised by 1H, 7Li, 13C NMR spectroscopy; 2 has been studied by variable temperature and DOSY NMR.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 53152-69-5 is helpful to your research., name: (1R,2R)-N1,N1,N2,N2-Tetramethylcyclohexane-1,2-diamine
