Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 29841-69-8, molcular formula is C14H16N2, introducing its new discovery. Recommanded Product: (1S,2S)-(-)-1,2-Diphenylethylenediamine
Correction: Polyfunctional Imidazolium Aryloxide Betaine/Lewis Acid Catalysts as Tools for the Asymmetric Synthesis of Disfavored Diastereomers (Journal of the American Chemical Society (2019) 141 (12029?12043) DOI: 10.1021/jacs.9b04902)
Page 12035 and Supporting Information pp S91?S94. It has come to our attention that the wrong initial concentration of 1a was erroneously used in two experiments of the ?same excess? protocol.1 The experiments were thus repeated (0.055 rather than 0.06 mol/L of 1a was erroneously used before), and an excellent overlay of the ?time-adjusted same excess? reaction profiles and the standard reaction profile, as previously presented, was found. This indicates that no significant catalyst deactivation takes place and that the active catalyst concentration remains constant during the catalytic reaction. The conclusions are thus not affected by the unintentional error. The corrected Figure 1 is shown below, and a corrected.(Figure Presented) Supporting Information file is available, in which pp S91?S94 have been replaced, in which the correct kinetic experiments are described, including raw data. We apologize for any inconvenience.
