    • Alternatively, the formation of the N -alkylsulfiliminium bromides 14 could be explained by reactions of the alkylamines with S -bromosulfonium salts being formed by initial bromine-to-sulfide additions. Here, however, this reaction path appears unlikely as all attempts to promote such process were unsuccessful leading to only complex product mixtures as revealed by NMR spectroscopy

    • Initially, an equimolar mixture of MeNH2, Br2, und t -BuOK (1.4 equiv each) was applied for the imidation of sulfide 8a. Under these conditions, the conversion of 8a was only moderate (59%), and besides sulfiliminium salt 14a small amounts (2%) of sulfoxide 15a were detected
