Facile benzo-ring construction via palladium-catalyzed functionalization of unactivated sp3 C-H bonds under mild reaction conditions.
A practical synthetic method for the annulation of benzo-rings by the intramolecular coupling of an aryl iodide and a methylene C-H bond is described. The palladium-catalyzed C-H functionalization isExpand
