The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.23190-16-1, Name is (1R,2S)-(−)-2-Amino-1,2-diphenylethanol, molecular formula is C6H5CH(NH2)CH(C6H5)OH. In a Article，once mentioned of 23190-16-1, COA of Formula: C6H5CH(NH2)CH(C6H5)OH
We report herein the asymmetric coupling of flow-generated unstabilized diazo compounds and propargylated amine derivatives, using a new pyridinebis(imidazoline) ligand, a copper catalyst and base. The reaction proceeds rapidly, generating chiral allenes in 10?20 minutes with high enantioselectivity (89?98 % de/ee), moderate yields and a wide functional group tolerance.
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.COA of Formula: C6H5CH(NH2)CH(C6H5)OH, you can also check out more blogs about23190-16-1
