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.
区域发散反应是快速获取分子多样性的一个令人着迷的工具。在此,我们报道了高价溴作为芳基前体的互补特征及其在过渡金属催化反应下提供邻位和间位取代的炔基化产物的行为。机理和计算研究表明了如何控制这些选择性。
