Chiral diene ligands: Conjugate addition of aryl boronic acids to cyclohexenone is catalysed by Rh complexes of the simple chiral diene (S)‐bicyclo[3.3.1]nona‐2,6‐diene in unexpectedly high ee. Insight into the reasons, and more generally the TS structure and pathways with other catalysts, was explored by using density functional theory. There was a gratifyingly good agreement between calculation and

环己烯酮上。通过使用密度泛函理论探索了原因,以及更普遍的与其他催化剂的
TS结构和途径。在计算和实验之间达成了令人欣喜的良好协议。缺乏明显的空间辨别力,加上
TS结构的系统变化,都牵涉到立体声电子学。
