distinct alkoxycarbonylation pattern via an in situ generated Fe2− catalyst is reported. This low-valent iron catalyst activates alkyl halides via a two-electrontransfer (TET) process, unlike previous reports where alkyl halides underwent a single electron transfer (SET). This reaction provides easy and efficient access to esters, and its mechanism will provide new ideas for the activation of alkyl halides
报道了通过原位生成的 Fe 2-催化剂产生的独特的烷氧基羰基化模式。这种低价铁催化剂通过双电子转移 (TET) 过程激活卤代烷,这与之前报道的卤代烷经历单电子转移 (SET) 不同。该反应为酯类的制备提供了简单高效的途径,其机理将为卤代烃在羰基化领域的活化提供新思路。

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。
