摘要

[FeIII(F20-tpp)Cl] (F20-tpp=meso-tetrakis(pentafluorophenyl)porphyrinato dianion) is an effective catalyst for imidoitrene insertion reactions using sulfonyl and aryl azides as nitrogen source. Under thermal conditions, aziridination of aryl and alkyl alkenes (16 examples, 60–95 % yields), sulfimidation of sulfides (11 examples, 76–96 % yields), allylic amidation/amination of -methylstyrenes (15 examples, 68–83 % yields), and amination of saturated CH bonds including that of cycloalkanes and adamantane (eight examples, 64–80 % yields) can be accomplished by using 2 mol % [FeIII(F20-tpp)Cl] as catalyst. Under microwave irradiation conditions, the reaction time of aziridination (four examples), allylic amination (five examples), sulfimidation (two examples), and amination of saturated CH bonds (three examples) can be reduced by up to 16-fold (24–48 versus 1.5–6 h) without significantly affecting the product yield and substrate conversion.
