Cycloaddition reactions of benzyne with olefins

Some novel cycloaddition reactions based on benzyne and olefins have been developed. These reactions were performed in the absence of a transition metal catalyst, and they displayed good yields. These cycloaddition reactions of benzyne with olefins provide effective routes for synthesizing benzocyclobutenes, biaryl compounds and 9,10-dihydrophenanthrene derivatives.
