Divergent reaction pathways for phenol arylation by arynes: Synthesis of helicenes and 2-arylphenols

Two reactions of phenols with arynes have been developed. If LiTMP base is employed, arynes generated from aryl chlorides react with phenols to form helicenes. o-Arylation of phenols can be achieved by employing tBuONa base in the presence of AgOAc. Direc
