A novel preparation of sulfilimines from the corresponding sulfoxides using the Burgess reagent is described. The reaction is general to dialkyl- and aryl alkyl sulfoxides and proceeds under mild conditions in benzene. A variety of protecting groups can be introduced on the nitrogen of the sulfilimine by choosing the appropriate Burgess reagent.

practical synthesis of arylsulfonamides from electron-rich aromatic compounds by using in situ generated N-sulfonylamine as the active electrophile. Substrates include derivatives of aniline, indole, pyrrole, furan, styrene and so on. The reaction proceeds under mild conditions and tolerates many sensitive functional groups such as alkyne, acetate, the trifluoromethoxy group or acetoxymethyl ester. Applications
