Sunday June 18th 2023 | In this class, we continue with studying p-conjugated systems in terms of their reactivity. In particular we will focus on pericyclic reactions (i.e., reactions that have a cyclic transition-state) that will be exemplified by the Diels-Alder reaction and the electrocyclization. These reactions are analyzed in terms of the Woodward/Hoffman Rules, for which will explore the molecular orbital basis. In this introductory class, we will explore first the Diels-Alder reaction and discover when these reactions are thermally or photochemically allowed and how this influences the corresponding stereoselectivity. Finally, introduce the steps necessary for constructing the correlation diagram that helps is understand when a reaction is thermally allowed. Notice that the first few minutes only my voice is heard due to a technical error with the camera.
