Synthetic Route of 20439-47-8, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 20439-47-8, name is (1R,2R)-Cyclohexane-1,2-diamine. In an article，Which mentioned a new discovery about 20439-47-8
The first C2-symmetric immobilized organocatalyst for asymmetric aldol reactions containing the (1R,2R)-bis[(S)-prolinamido]cyclohexane unit tagged with two imidazolium+/PF6- ion pairs has been synthesized. In its presence, (hetero)aromatic aldehydes reacted with linear or cyclic ketones in aqueous media to yield chiral aldols with high diastereo- and enantioselectivities and the catalyst could be recovered and reused at least 10 times without any decrease in the reaction rate or selectivity. The first C2-symmetric recoverable organocatalyst containing a (1R,2R)-bis[(S)-prolinamido]cyclohexane unit tagged with two imidazolium cations has been synthesized and applied to asymmetric aldol reactions in aqueous media. High yields and ee values of chiral aldols were obtained with the catalyst up to 10 cycles.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.20439-47-8. In my other articles, you can also check out more blogs about 20439-47-8
