A light-promoted Ni-catalyzed cyanation of arylhalides employing 1,4-dicyanobenzene as a cyanating agent is reported. A broad array of aryl bromides, chlorides, and druglike molecules could be converted into their corresponding nitriles (65 examples). Mechanistic studies suggest that upon irradiation, the oxidative addition product Ni(II)(dtbbpy)(p-C6H4CN)(CN) undergoes homolytic cleavage of the Ni–aryl
报道了使用 1,4-二氰基苯作为氰化剂的光促进 Ni 催化的芳基卤化物氰化反应。广泛的芳基溴化物、氯化物和药物样分子可以转化为相应的腈(65 个例子)。机理研究表明,在辐照下,氧化加成产物 Ni(II)(dtbbpy)( p -C 6 H 4 CN)(CN) 发生 Ni-芳基键均裂,生成芳基自由基和 Ni(I) -CN 物质,后者引发随后的氰化反应。
