Synthesis of Dibenzopyranones through Palladium‐Catalyzed Directed C–H Activation/Carbonylation of 2‐Arylphenols

Dibenzopyranones were synthesized by a palladium-catalyzed phenol-directed C–H activation/carbonylation of 2-phenylphenol derivatives in the presence of CO. Pd(OAc)2 was used as a catalyst and Cu(OAc)2 as a catalytic oxidant in the presence of air.
