Biaryls were synthesized via a novel visible-light-promoted Gomberg–Bachmann reaction that does not require a photosensitizer or any metal reagents. The formation of an electron donor–acceptor complex between aryl diazonium salts and pyridine allows, under visible-light irradiation, the synthesis of biaryls in moderate-to-high yields.

可见光促进的，无催化剂的Gomberg-Bachmann反应：联芳烃的合成

联芳基是通过不需要光敏剂或任何金属试剂的新型可见光促进的Gomberg-Bachmann反应合成的。在芳基重氮盐和吡啶之间形成电子供体-受体配合物，可以在可见光照射下以中等至高收率合成联芳基。
