Regiodivergent reactions are a fascinating tool to rapidly access molecular diversity. Herein we reported the complemental character of hypervalent bromines, as aryne precursors and their behavior under transition metal-catalyzed reactions to furnish both ortho- and meta-substituted alkynylation products. Mechanistic and computational studies show how these selectivities are controlled.
