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

Aryldiazo substituents were used in nucleophilic aromatic substitution reactions of halogens. The Ph-N=N- group activates ortho fluorine atoms toward alkylthiolation under mild conditions. In contrast, the Me(2)N-C(6)H(4)-N=N- group has virtually no activation effect in nucleophilic aromatic substitution, and serves as
