In a preparation of N-alkyl-substituted sulfoximines from sulfides, in situ generated N-bromoalkylamines serve as readily accessible imidating agents leading to N-alkylsulfiliminium bromides that are subsequently oxidized providing the desired products. This unprecedented one-pot imidation/oxidation sequence provides gram quantities of product in a short period of time avoiding the use of toxic alkylating reagents.
