A mild and efficient copper-catalyzed borylation of electron deficient allenoates using an sp2âsp3 mixed hybridized diboron regioselectively installs a boron moiety on the β-position with exclusive (Z)-double bond geometry.
使用 sp2âsp3 混合杂化的二硼区域选择性地在δ-位上安装了一个硼分子,该硼分子具有独占的 (Z) 双键几何结构,从而温和、高效地催化了缺电子异戊酸酯的硼酸化反应。
