nitride (mpg-CN) and a homogeneous nickel catalyst with visible-light irradiation at room temperature affords the C(sp2)–C(sp3) cross-coupling of aryl halides and potassium alkyl trifluoroborates by single electron transmetallation. Like the homogeneously catalyzed protocol, the reaction is compatible with a variety of functional groups including electron-donating and electron-withdrawing aryl and heteroaryl
异质有机半导体介孔石墨碳氮化物(mpg-CN)和均相镍催化剂与室温可见光辐射的协同结合可提供C(sp 2)–C(sp 3)通过单电子金属转移将芳基卤化物和烷基三氟硼酸钾交叉偶联。像均相催化方案一样,该反应与多种官能团兼容,包括给电子和吸电子的芳基和杂芳基部分。而且,该协议允许将烯丙基安装在(杂)芳烃上,从而扩大了方法的范围。异质mpg-CN光催化剂很容易从反应混合物中回收并重复使用数次,从而为这种类型的光催化键形成反应的大规模工业应用铺平了道路。
