abundance, and potential for distinct and complementary reactivity patterns. Meanwhile, alkyl bromides as well as low nucleophilic amides and indoles are considered to be particularly challenge substrates for carbonylation reactions. Herein, we report an iron-catalyzed carbonylative coupling of unactivated alkylhalides with amines, amides, and indoles to assemble amide structural units, affording various
铁催化的羰基化反应在我们倡导可持续发展的化学界非常受欢迎,因为它成本低、资源丰富,并且具有独特和互补反应模式的潜力。同时,烷基溴以及低亲核性酰胺和吲哚被认为是羰基化反应特别具有挑战性的底物。在此,我们报告了未活化的烷基卤化物与胺、酰胺和吲哚的铁催化羰基化偶联以组装酰胺结构单元,提供各种酰胺、酰亚胺和N- 具有优异产率和前所未有的官能团相容性的酰基吲哚。值得注意的是,我们的方法也代表了 Fe 催化的卤代烷氨基羰基化的例子。我们的初步机理研究表明反应途径是底物依赖性的:当使用烷基碘时,羰基化通过自由基途径进行;而当烷基溴化物作为亲电子试剂时,会发生双电子转移 (TET) 过程。
Iodine-mediated aryl transfer reaction from arylhydrazine hydrochlorides to nitriles
An iodine-promoted, metal-, base-, and solvent-free cross-couplingreaction was developed for the synthesis of various useful secondary amides via an aryl N-addition reaction of aryl groups to cyano groups. This aryl transfer reaction proceeds with arylhydrazine hydrochlorides serving as the aryl donors. A labelling experiment shows that the N atom in the product comes from the cyano group of the nitriles
