The copper-mediatedtandem oxidative C(sp2)–H/C(sp)–H cross-coupling and intramolecular annulation of arenes with terminal alkynes has been developed, which offers a highly efficient approach to the 3-methyleneisoindolin-1-one scaffold. In this oxidative coupling process, Cu(OAc)2 acts as both the promoter and the terminal oxidant. This protocol features a wide substrate scope; high functional group
