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.
