摘要

炔烃半加氢反应的关键之一是非对映选择性控制。在本期《化学催化》（Chem Catalysis）杂志上，Werlé 等人介绍了一种基于铑的系统，该系统可根据溶剂的不同生成(Z)-或(E)-烯烃。在(Z)-半加氢反应中观察到了外球体机理，而(Z)→(E)异构化反应则是通过内球体机理进行的。

Solvent-controlled diastereoselectivity of alkyne semihydrogenation

One of the crucial aspects of alkyne semihydrogenation is diastereoselectivity control. In this issue of Chem Catalysis, Werlé et al. described a rhodium-based system that may lead to (Z)- or (E)-alkenes, depending on the solvent. The outer-sphere mechanism was observed for (Z)-semihydrogenation while (Z)→(E) isomerization proceeds via the inner-sphere mechanism.
