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

摘要

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.
