perfluoroalkylated sulfoxides with trifluoromethanesulfonic anhydride behaves as highly electrophilic entities. Their reaction with nitriles allows a Ritter-like process leading to the new fluorinated acylsulfilimines 1–21 after hydrolysis. This flexible methodology allows some variation of both the sulfoxide and nitrile components. Derived acylsulfoximines 22–25 or free sulfoximines 26–28 could be selectively

This work describes the preparation of an aliphatic series of the N-trifluoromethanesulfonyl-S-trifluoromethyl-S-sulfoximine group. The key step of the synthesis is the imination of fluorinated sulfoxides under experimental conditions, which avoid cleavage of the alkyl group. The formation of sulfoximines 6 and 15 allows the preparation of various fluorinated sulfoximines having strong electron withdrawing
