Приложения

This compound is primarily used as an organic synthesis intermediate, particularly in the synthesis of conjugated organic materials. It is commonly utilized in Suzuki coupling reactions to introduce phenylanthracene rings into conjugated materials, thereby altering their luminescence and structural properties. Additionally, it serves as an intermediate in the production of Organic Light-Emitting Diodes (OLEDs).

Синтез

The conventional synthesis of 10-Phenylanthracene-9-boronic acid involves starting with 9-bromo-10-phenylanthracene. Under strong basic conditions, the bromine atom on the anthracene ring is removed to generate an aryl lithium reagent. This reagent is then reacted with trimethyl borate or triisopropyl borate, followed by hydrolysis to yield the boronic acid compound. This route is widely used and efficient for synthesizing arylboronic acids.
