Pericyclic reactions Guides d'étude, Notes de cours & Résumés

### Pericyclic Reactions **Definition:** - A class of organic reactions that proceed via a concerted mechanism involving cyclic transition states. **Types:** 1. **Cycloaddition:** - Two π-systems combine to form a ring. - Example: Diels-Alder reaction, forming a six-membered ring. 2. **Electrocyclic Reactions:** - A conjugated π-system converts to a ring or vice versa. - Example: Ring closure of hexatriene to form cyclohexadiene. 3. **Sigmatropic Rearrangements:**...
