The electronic nature of the ligand plays a crucial role in the palladium-catalysed allylation of amines with allylic alcohols. The better the ligand is as a π acceptor, the more active the catalyst. Experiments with a series with mono- and bidentate ligands featuring phosphanes and phospholes applied in the catalytic allylation of aniline clearly demonstrate this. Bolstered by DFT calculations, we

配体作为 π 受体越好,催化剂的活性就越高。一系列具有单齿和双齿
配体的实验清楚地证明了这一点。在 DFT 计算的支持下,我们为该过程设计了一种新的高效催化剂,该催化剂带有强 π 受体 1,2,5-三苯基
