A Simple and Versatile Synthesis of 1,2-Diarylacenaphthylenes via Suzuki-Miyaura Coupling, and its Application in the Synthesis of a New ­Acenaphthylene-1,2-bis(p-quinone methide) Derivative

1,2-Diaryl-substituted acenaphthylene derivatives were prepared simply via Suzuki-Miyaura coupling in good or excellent yields. By applying this method, acenaphthylene-1,2-bis( P-quinone methide) with two 3,5-di- TERT-butyl-4-oxocyclohexadienylidene units, which is a stable deep purple crystalline substance with a very broad absorption in the whole visible region and relatively low -reduction potential, was prepared and characterized.
