The oxyboration of arynes was achieved for the first time. A series of 2-aryl-1,3,2-dioxaborolane derivatives were reacted with aryne precursors in the presence of CsF to give the corresponding ring-expanded seven-membered borinic acid esters via selective boron–oxygen bond activation. Preliminary experimental mechanistic studies and density functional theory (DFT) calculations suggest that this unprecedented
首次实现了芳炔的硼氧化。一系列2-芳基-1,3,2-二氧硼杂硼烷衍生物在CsF存在下与芳基前体反应,通过选择性硼-氧键活化得到相应的扩环七元硼酸酯。初步实验机理研究和密度泛函理论 (DFT) 计算表明,这种前所未有的芳基硼氧化反应是通过芳基硼酸盐与 CsF 形成硼酸盐复合物进行的,然后将芳基插入硼-氧键中。
