Application of 20439-47-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.20439-47-8, Name is (1R,2R)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 20439-47-8
Chiral dimeric Mn(III) salen complex with 1R, 2R-(-)-diaminocyclohexane collar was immobilized on short channel large pore sized silica through a long linker of {(CH2)3-NH-melamine-piperazine} to investigate its performance in enantioselective epoxidation of chromenes, indene, styrene and cis beta-methyl styrene in the presence of pyridine N-oxide (PyNO) as an axial base using aqueous NaOCl as an oxidant at 0C. The immobilized catalyst system showed high turnover frequency (TOF) and enantioselectivity for the smaller and bulkier alkenes like styrene, indene, 2,2-dimethylchromene and 6-cyano-2,2-dimethylchromene (ee up to 98%). These results are the best reported for heterogeneous catalyst under biphasic reaction conditions and were comparable to the dimeric Mn(III) salen system under homogeneous condition. The performance of the immobilized catalyst was retained for six reuse experiments. This protocol was extended to the synthesis of an antihypertensive drug (S)-Levchromakalim (ee 98%) at 1 g level.
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 20439-47-8 is helpful to your research. Application of 20439-47-8
