General description
1-Bromo-4-chloro-2-fluorobenzene is a polyhalo substituted benzene. It undergoes Suzuki coupling with 2-cyanoarylboronic esters to form the corresponding biphenyls. These biphenyls are the precursors for synthesizing 6-substituted phenanthridines.† The enthalpy of vaporization at boiling point (467.15K) of 1-bromo-4-chloro-2-fluorobenzene is 40.737kjoule/mol.{4}
Application
1-Bromo-4-chloro-2-fluorobenzene may be used in the preparation of benzonorbornadiene derivative. It may also be used as a starting material in the multi-step synthesis of AZD3264, an IKK2 (inhibitor of nuclear factor κ-B kinase-2) inhibitor.

This report details the synthesis of several benzonorbornadienes by Diels--Alder cycloaddition of cyclopentadiene derivatives with substituted benzyne intermediates, which were generated by low-temperature metal--halogen exchange of halobenzenes. General conditions were developed, allowing synthesis of most benzonorbornadienes described herein at the
