[reaction: see text] Silver salts in the presence of a chelating ligand efficiently catalyze the stereospecific imination of sulfoxides and sulfides with sulfonylamides and PhI(OAc)(2) to afford sulfoximines and sulfilimines, respectively, in good yields.

[reaction: see text] The Fe(III)-catalyzed imination of sulfoxides and sulfides with sulfonylamides in the presence of iodinanes has been investigated. The best results were obtained when Fe(acac)(3) was used as a catalyst in combination with iodosylbenzene, providing an effective alternative (stereospecific) access to sulfoximines and sulfilimines.

The challenging imination of benzyl-, sterically demanding alkyl-, and heteroaryl-substituted sulfoxides has been studied. Iron(II) triflate was identified as a highly efficient and robust catalyst for sulfur imination reactions. A variety of sulfoxides and sulfides were efficiently iminated with sulfonyliminoiodinanes (PhI═NSO2R) at room temperature to give the corresponding sulfoximines and sulfilimines

range of sulfoxides possessing functionalised side-chains using mesitylene sulfonyl hydroxylamine or iminoiodane reagents is discussed. The use of iminoiodane reagents possessing removable protecting groups (p-nosyl and Ses) is reported along with conditions for the deprotection of the sulfoximine adducts.
