Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Product Details of 126456-43-7, Name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, belongs to chiral-nitrogen-ligands compound, is a common compound. Product Details of 126456-43-7Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In an article, authors is Lang, Kai, once mentioned the new application about Product Details of 126456-43-7.
Base-functionalized aza-bis(oxazoline) ligands were prepared to explore the concept of dual activation through the Lewis acid and a tethered tertiary amine base. The catalytic activity of the Cu complex was evaluated for the asymmetric Henry reaction. Compared with a corresponding unfunctionalized copper complex with external 1-benzyl-4-ethylpiperazine base, the ethylpiperazine- functionalized aza-bis(oxazoline) copper catalyst resulted in rate acceleration (2.5 times) as well as improved enantioselectivity (72% ee vs 92% ee).
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. Product Details of 126456-43-7, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 126456-43-7, in my other articles.
