Coupling aromatic heteronucleophiles to arenes is a common way to assemble drug‐like molecules. Many methods operate via nucleophiles intercepting organometallic intermediates, via Pd‐, Cu‐, and Ni‐catalysis, that facilitate carbon‐heteroatom bond formation and a variety of protocols. We present an alternative, unified strategy where phosphonium salts can replicate the behavior of organometallic intermediates
将芳香族异核试剂与芳烃偶联是组装类药物分子的常见方法。许多方法通过亲核试剂拦截有机金属中间体,通过 Pd、Cu 和 Ni 催化来进行,从而促进碳杂原子键的形成和各种方案。我们提出了一种替代的、统一的策略,其中鏻盐可以复制有机金属中间体的行为。在一组狭窄的反应条件下,多种芳香族杂核亲核试剂可以与吡啶和二嗪偶联,这在金属催化偶联中经常出现问题,例如在具有多个极性官能团的复杂结构中无法获得(假)卤化物前体。

organic synthesis. A general method for the direct deoxygenative cross-coupling of free alcohols must overcome several challenges, most notably the in situ cleavage of strong C–O bonds3, but would allow access to the vast collection of commercially available, structurally diverse alcohols as coupling partners4. We report herein a metallaphotoredox-based cross-coupling platform in which free alcohols
