A distinct alkoxycarbonylation pattern via an in situ generated Fe²⁻ catalyst is reported. This low-valent iron catalyst activates alkyl halides via a two-electron transfer (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 in the field of carbonylation.

通过双电子转移过程铁催化烷基溴烷氧基羰基化

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。
