Organic Chemistry - Electrocyclic Reactions | 16.7 Organic Chemistry

Chad provides a comprehensive lesson on Electrocyclic Reactions, ring-openings and ring closures. He begins by comparing thermal and photochemical conditions for a ring closure. He then shows how disrotatory or conrotatory rotation in the transition state needs to lead to constructive overlap for a reaction to be 'allowed.' He then summarizes the Woodward-Hoffmann rules as they pertain in electrocyclic reactions. Chad concludes the lesson by showing how to predict the stereochemistry of the products of electrocyclic reactions.
