involved in the development of alkene hydro- and difunctionalization reactions, where β-hydride elimination can be controlled. We report herein the development of an asymmetric palladium-catalyzed hydroarylation, which yields diarylmethine products in up to 75% ee. Interestingly, a linear free energy relationship is observed between the steric bulk of the ligand within a certain range and the ee of the
烯烃是用于有机转化的理想且用途广泛的起始材料,也是众所周知的钯催化底物。通常,这些反应会通过β-氢化物消除形成新的烯烃产物。与这种情况相比,我们的实验室参与了烯烃加氢和双官能化反应的开发,其中可以控制 β-氢化物的消除。我们在此报告了不对称钯催化加氢芳基化的发展,该反应可产生高达 75% ee 的二芳基次甲基产物。有趣的是,在一定范围内的配体空间体积与反应的 ee 之间观察到线性自由能关系。
