The sequential transformation of arynes into ortho-disubstituted arenes is achieved by a one-pot procedure using formamides and dialkylzincs. This reaction proceeded via a route involving the trapping reaction of the formal [2 + 2] cycloaddition adducts or quinone methides generated by the insertion of arynes into the C═Obond of amides.
