Chemical Reactions and Mechanisms

Cotrimerization of arynes and electron-deficient alkenes selectively affords dihydrophenanthrenes or ortho-olefinated biaryls, depending on the catalytic system employed. Our findings support a mechanism involving benzyne and a metallacycloheptadiene as key intermediates.
