• Iodide as an Activating Agent for Acid Chlorides in Acylation Reactions

  Acid chlorides can be activated using a simple iodide source to undergo nucleophilic attack from a variety of relatively weak nucleophiles. These include Friedel–Crafts acylation of N-methylpyrroles, N-acylation of sulfonamides, and acylation reactions of hindered phenol derivatives. The reaction is believed to proceed through a transient acid iodide intermediate.

  可以使用简单的碘源活化酰氯，使其受到各种相对较弱的亲核试剂的亲核攻击。其中包括N-甲基吡咯的Friedel-Crafts酰化，磺酰胺的N-酰化以及受阻酚衍生物的酰化反应。据信该反应通过过渡性碘酸中间体进行。

  from aldehydes by an iron-catalyzed nitrene insertion reaction has been developed. Both aryl and aliphatic aldehydes can directly afford the corresponding amides with an iron(II)-terpyridine (tpy) complex formed in situ as catalyst, and PhI=NTs as nitrogen source under mild reaction conditions. An ESI-MS study revealed the formation of [Fe(tpy) 2 (NTs)] 2+ as a reaction intermediate.

  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。

  A catalyst-free protocol has been developed for amidation of alkyl aromatics and aldehydes using TsNBr(2)via a nitrene transfer process in the presence of a base in excellent yield within a short time. The reaction was found to be selective for secondary and tertiary benzylic C-H bonds and C-H bonds of aldehydic groups.

  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.
