have been developed. The former route enables C4-arylation in a highly efficient and mild manner and the latter route provides an alternative straightforward protocol for synthesis of C2/C4 disubstituted indoles. The mechanism studies imply that the different reaction pathways were tuned by the distinct acid additives, which led to either the Pd(I)–Pd(II) pathway or Pd(II) catalysis.
吲哚的高效 C4-芳基化和多米诺 C4-芳基化/3,2-羰基迁移已经开发出来。前一种路线能够以高效且温和的方式实现C4-芳基化,后一种路线为合成C2/C4二取代
吲哚提供了一种替代的简单方案。机理研究表明不同的反应途径是通过不同的酸添加剂调节的,从而导致 Pd()–Pd( II ) 途径或 Pd( II ) 催化。
