Abstract
Arynes are important synthetic intermediates that are usually generated under alkaline conditions. We developed a method for generating arynes using two hydroxy compounds as activators. o-Triazenylarylboronic acids generate (hetero)arynes when activated by a combination of ethylene glycol, pinacol, and p-nitrophenol; these arynes then react with a range of arynophiles under slightly acidic conditions that complement the conventional basic conditions with unique chemoselectivities observed even in the presence of excess hydroxy compounds.
