  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.

  efficient one‐pot synthesis of S‐perfluoroalkylated NH‐sulfoximines from sulfides has been developed using phenyliodine diacetate (PIDA) and ammonium carbamate. Remarkable rate enhancement with trifluoroethanol was observed, presumably due to H‐bonding effects. These mild and metal‐free conditions are compatible with ‐CH2F, ‐CFCl2, ‐CF2H, ‐CF2Br, ‐C4F9, and ‐CF3 groups, in both the alkyl‐ and aryl series. Based

  使用二碘苯基碘二乙酸酯（PIDA）和氨基甲酸铵开发了一种通用的由硫化物有效地单锅合成S-全氟烷基化NH-亚磺酰亚胺的方法。观察到三氟乙醇显着提高了速率，这可能是由于氢键作用所致。这些温和且无金属的条件在烷基和芳基系列中均与-CH 2 F，-CFCl 2，-CF 2 H，-CF 2 Br，-C 4 F 9和-CF 3基团兼容。根据19 F NMR分析，λ 6，提出了-acetoxysulfanenitrile中间体。

  New electrophilic fluoroalkylating agents based on the sulfoximine skeleton as a common platform are described. We demonstrate the importance of the activating group, attached to the nitrogen, and its specificity for the fluorinated group to be delivered. As an application, a variety of unknown dichlorofluoro, bromodifluoro, and trifluoromethyl alkynes have been prepared using these reagents.
