Chlorinated organic backbones constitute important components in existing biologically active chemicals, and they are extraordinary useful intermediates in organic synthesis. Herein, an operationally simple and sustainable halodecarboxylation protocol via halogen-atom transfer (XAT) as a key step is presented. The method merges a metal-free photoredox system with (diacetoxyiodo)benzene (PIDA) as a
氯化有机主链是现有生物活性化学品的重要组成部分,它们是有机合成中非常有用的中间体。在此,提出了一种通过卤素原子转移(XAT)作为关键步骤的操作简单且可持续的卤代脱羧方案。该方法将无金属光氧化还原系统与作为高价碘试剂的(二乙酰氧基碘)苯(PIDA)相结合,使用1,2-二卤乙烷作为卤素源,以有效的方式提供卤代烷烃。该协议的可持续性通过重要的废物回收协议以及原子经济和碳效率参数得到强调。
