Divergent catalysis is an emerging field whereby access to structurally diverse compounds from a common precursor is achieved through controlled reaction pathways. Herein we present an unusual example of π-acid catalyst dependent selectivity in the cycloisomerization of alkene-tethered sulfonium ylides. Computational mechanistic studies revealed how the ability of palladium to cycle through oxidation states largely controls the selectivity.

锍叶立德环异构化反应中依赖于催化剂的选择性†

发散催化是一个新兴领域,通过受控的反应途径可以从共同的前体中获得结构多样的化合物。在这里,我们提出了一个不寻常的例子,即在烯烃束缚锍叶立德的环异构化中依赖于 π-酸催化剂的选择性。计算机理研究揭示了钯在氧化态中循环的能力如何在很大程度上控制选择性。
