A nickel-catalyzed heteroannulation has been developed where o-haloanilines react with alkynes to afford 2,3-disubstituted indoles. IPr (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) was found to be an effective ligand for the reaction.
已开发一种镍催化的杂环合成反应,其中邻卤代苯胺与炔烃反应生成2,3-二取代吲哚。发现IPr(1,3-双(2,6-二异丙基苯基)咪唑-2-亚氮基)是该反应的有效配体。
