Epoxidation of Alkenes with Peracids

Epoxidation of Alkenes with Peracids: Mechanism

The fact that no ionic intermediates are observed during the epoxidation with peracids indicates that the reaction follows a one-step mechanism. The participating bonds are broken and the new bonds are formed simultaneously. In the transition state, the oxygen atom with the partial positive charge interacts with the electron-rich double bond and a hydrogen bond is simultaneously formed between the hydrogen atom and the carbonyl oxygen.
