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。
