In this Communication, the diastereomeric ratio (d.r.) of 2′ was reported to be >99:1, which was determined by 19F NMR spectroscopy using CHCl3 as solvent. During recent investigations on the deuteration of α-fluoro sulfoximines with various N-substituents, the authors found that the reported d.r. of 2′ (>99:1) was incorrect. This error was caused by the coincidental overlap of 19F NMR peaks of two diastereomers of 2′ (see the Supporting Information accompanying the Communication, pages 3–4). The correct d.r. of 2′ should be 68:32, as determined by 1H NMR spectroscopy in CDCl3 (see the Supporting Information accompanying this Corrigendum). This corrected d.r. value was also confirmed by the 19F NMR measurement of 2′ using [D6]DMSO as solvent (see the Supporting Information accompanying this Corrigendum). This correction does not affect the results and conclusions in other parts of the Communication. The authors sincerely apologize for this mistake.
