摘要：

Epoxidation is exothermic with −19.3 kcalmol−1 [Eq. (b)] instead of endothermic with +27.7 kcal mol−1 [Eq. (a)] when carried out in the presence of Li⊕. This emerged from demanding ab‐initio calculations for this model system. Since Li⊕‐catalysis is largely a result of an electrostatic effect, other metal ions should also be able to act as catalysts for epoxidation. (Formula Presented.)
