18671-97-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 18671-97-1, Name is 2,6-Dichloroquinoxaline, molecular formula is C8H4Cl2N2. In a Article, authors is Mrsic, Natasa£¬once mentioned of 18671-97-1
Asymmetric hydrogenation of quinoxalines catalyzed by iridium/PipPhos
A catalyst made in situ from the (cyclooctadiene)iridium chloride dimer, [Ir(COD)Cl]2, and the monodentate phosphoramidite ligand (S)-PipPhos was used in the enantioselective hydrogenation of 2- and 2,6-substituted quinoxalines. In the presence of piperidine hydrochloride as additive full conversions and enantioselectivities of up to 96% are obtained.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 18671-97-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 18671-97-1, in my other articles.
