Nickel-catalyzed decarboxylative coupling reactions between aryl alkynyl carboxylic acids and arylboronic acids were developed. When aryl alkynyl carboxylic acids were reacted with arylboronic acids in the presence of NiCl2 (10 mol %), 2,2′-bipyridine (20 mol %), Na2CO3 (1.0 equiv), and Ag2CO3 (1.0 equiv) in DMF at 80 °C for 18 h, the corresponding diaryl alkynes products were formed in moderate to
开发了镍催化的芳基炔基羧酸和芳基硼酸之间的脱羧偶联反应。在NiCl 2(10 mol%),2,2'-联吡啶(20 mol%),Na 2 CO 3(1.0当量)和Ag 2 CO 3(1.0 )存在下,芳基炔基羧酸与芳基硼酸反应当量)在DMF中于80°C放置18 h,相应的二芳基炔烃产物以中等至良好的产率形成。
