N-fluorobis[(perfluoroalkyl)sulfonyl]imides, CF3SO2N(F)SO2Rf (Rf′=C4F9, C6F13, C8F17) and (C4F9SO2)2NF, were prepared by direct fluorination of corresponding N–H compounds using elemental fluorine without a solvent in good to excellent yields. All of these N–F compounds are electrophilic fluorination agents and can easily deliver “F+” to certain molecules. Their reactions with aromatic rings, beta-diketones
N-氟双[(全氟烷基)磺酰基]酰亚胺,CF 3 SO 2 N(F)SO 2 R f(R f '= C 4 F 9,C 6 F 13,C 8 F 17)和(C 4 F 9 SO 2)2 NF,是通过在不使用溶剂的情况下,使用元素氟直接氟化相应的N–H化合物而制备的,具有良好至极好的收率。所有这些N–F化合物都是亲电氟化剂,可以轻松提供“ F +对于某些分子。研究了它们与芳环,β-二酮和烯烃的反应,以比较它们的氟化能力。
