Electric Literature of 144222-34-4, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 144222-34-4, Name is N-((1R,2R)-2-Amino-1,2-diphenylethyl)-4-methylbenzenesulfonamide, molecular formula is C21H22N2O2S. In a Article，once mentioned of 144222-34-4
Based on (1R,2R)-(+)-(1,2)-DPEN skeleton, a series of primary amine-sulfamide bifunctional catalysts were synthesized, which exhibited excellent catalytic performance in the Michael addition of acetone to beta-nitrostyrene. Therefore, a trifunctional heterogeneous catalyst was designed and prepared by simple N-sulfonyl reaction of (1R,2R)-(+)-(1,2)-DPEN and sulfonyl chloride resin. It was employed for the aforementioned addition without any additive and satisfactory results (80.5% conversion; 84.3% ee) were obtained. Meanwhile, the structural and textural properties of the catalyst were characterized by infrared spectroscopy (FT-IR), elemental analysis, SEM, and N2 adsorption and desorption experiments. Finally, the generality of the catalyst was investigated.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 144222-34-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 144222-34-4, in my other articles.
