Palladium Catalyzed C–I and Vicinal C–H Dual Activation of Diaryliodonium Salts for Diarylations: Synthesis of Triphenylenes
2018
Using the synthetic strategy of palladium-catalyzed dual activation of both C–I and vicinal C–H bonds of diaryliodonium salts, we report an approach for direct diarylations of 2-bromobiphenyls or bromobenzenes. As a result, a wide range of triphenylenes with various substituents have been synthesized in good yields. These triphenylenes are expected to be employed in the “bottom-up” synthesis of functional aromatic molecules in material science.
