Functionalized S-perfluorinated sulfoximines: Preparation and evaluation in catalytic processes
摘要:
N-substituted S-perfluoroalkylated sulfoximines were synthesized from the NH sulfoximines either by a copper coupling reaction with aryl halides or by a reaction with electrophilic substrates. The procedure allowed the preparation of N,N'-bridged bis sulfoximines and of thioureas. The potential of these new sulfoximines was evaluated in different catalytic processes. (C) 2015 Elsevier B.V.

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
