Sulfoximines are tetracoordinate organosulfur compounds isoelectronic to sulfones. The synthetic application of these attractive organosulfur compounds have not been fully explored.'Johnson et al. revealed that a-sodio derivatives of N-(arylsulfony1) sulfoximines are useful nucleophilic alkylidene transfer reagents in the conversion of aldehydes and ketones to the corresponding oxiranes.'Several synthetic procedures for N-(arylsulfony1) ...
