  铁催化的腈插入反应轻松构建酰胺化合物

  摘要：

  已经开发了一种通过铁催化的氮烯插入反应从醛构建酰胺化合物的简便方法。在温和的反应条件下，芳基和脂肪醛都可以直接得到相应的酰胺，以原位形成的铁（II）-三联吡啶（tpy）配合物作为催化剂，PhI=NTs作为氮源。ESI-MS 研究揭示了 [Fe(tpy) 2 (NTs)] 2+ 作为反应中间体的形成。

• Iron(II)-Catalyzed Amidation of Aldehydes with Iminoiodinanes at Room Temperature and under Microwave-Assisted Conditions

  A method for the amidation of aldehydes with PhI=NTs/PhI=NNs as the nitrogen source and an inexpensive iron(II) chloride + pyridine as the in situ formed precatalyst under mild conditions at room temperature or microwave assisted conditions is described. The reaction was operationally straightforward and accomplished in moderate to excellent product yields (20-99%) and with complete chemoselectivity with the new C-N bond forming only at the formylic C-H bond in substrates containing other reactive functional groups. By utilizing microwave irradiation, comparable product yields and short reaction times of 1 h could be accomplished. The mechanism is suggested to involve insertion of a putative iron-nitrene/imido group to the formylic C H bond of the substrate via a H-atom abstraction/radical rebound pathway mediated by the precatalyst [Fe(py)(4)Cl-2] generated in situ from reaction of FeCl2 with pyridine.
