Reference of 23190-16-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 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
Bifunctional asymmetric phase-transfer catalysts bearing multiple hydrogen-bonding donors have rarely been explored. The first quaternary ammonium type of these catalysts derived from cinchona alkaloids were readily prepared and found to be highly efficient catalysts for asymmetric nitro-Mannich reactions of amidosulfones. Compared with previous reports, very broad substrate generality was observed, and both enantiomers of the products were achieved in high enantio- and diastereoselectivity (90-99% ee, 13:1 to 99:1 dr).
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 23190-16-1 is helpful to your research., Reference of 23190-16-1
