combination with a stoichiometric amount of Ag2CO3 has been established for the decarboxylativeCHbondarylation of thiophenes to give 2‐arylthiophenes (see scheme; Cy=cyclohexyl). Electron‐rich, electron‐deficient, and heterocyclic benzoic acids can be used as the arylating reagent and a broad range of substituents on the thiophene are tolerated.
已经建立了一种有效的方法,该方法涉及将Pd / PCy 3催化剂与化学计量的Ag 2 CO 3结合使用,以使噻吩进行脱羧化的C de H键芳基化反应,生成2-芳基噻吩(参见方案; Cy =环己基)。富电子,缺电子和杂环苯甲酸可以用作芳基化试剂,噻吩上的各种取代基是可以耐受的。
