The copper(II)-promoted C–C bond formation from the coupling of two C(sp3)–H bonds that are adjacent to a carbonylgroup was achieved. This protocol offers a simple and efficient approach to 2,3-disubstituted 1,4-diketones and tetrasubstituted furans. This method features a wide substrate scope and high functional group tolerance.

Silver‐catalyzedcoupling of twoCHgroups to form 1,4‐diketones have been developed for the first time. The resultant ketones then undergo cyclization to synthesize tetrasubstitutedfurans, thiophenes, and pyrroles from benzyl ketone derivatives in a one‐pot reaction process. This highly‐efficient synthetic method, which utilizes air as the terminal oxidant and readily accessible starting materials
