Biphenyl-4,4'-diboronic acid is used in the preparation of cycloparaphenylenes through Suzuki coupling. It is also employed in the synthesis of 1,3,2-diazaboroine derivatives, which is useful for organic thin-film transistor applications. It plays an important role in the preparation of arylboronates from reactions with catechol, dihydroxynaphthalene and diaminobenzenedithiol, which finds application as organic field-effect transistors and light emitting diodes.


Incompatible with strong oxidizing agents.
