The synergistic combination of a heterogeneous organic semiconductor mesoporous graphitic carbon 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 moieties. Moreover, this protocol allows the installation of allyl groups onto (hetero)arenes, enlarging the scope of the method. The heterogeneous mpg-CN photocatalyst is easily recovered from the reaction mixture and reused several times, paving the way for larger-scale industrial applications of this type of photocatalytic bond-forming reactions.

光-镍-双催化C（sp ²）-C（sp ³）交联反应与中孔石墨烯碳氮作为多相有机半导体光催化剂

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。
