A rhodium-catalyzed annulative coupling of (2-arylphenyl)boronic acids with alkynes has been developed for the facile construction of phenanthrene frameworks. The reaction proceeded without external bases, and dioxygen worked as a terminal oxidant. Deuterium-labeling experiments indicated the involvement of five-membered rhodacycle intermediates.
已经开发了铑催化的(2-芳基苯基)硼酸与炔烃的环状偶联,以方便地构建菲骨架。反应在没有外部碱的情况下进行,双氧作为末端氧化剂。氘标记实验表明五元红环中间体的参与。
