An important class of reactions in Organic Chemistry are Pericyclic Reactions. In a cyclic arrangement, bonds are broken and formed in an alternating fashion. Pericyclic Reactions proceed via aromatic transition states. This trajectory contains the complete collection of VLUs on Pericyclic Reactions.
Learning Units of the Tutorial
This learning unit gives an introduction to the large field of pericyclic reactions and their systematics and selection rules.
This learning unit explains the topological method to determine the aromaticity of transition states according to Ewans, Dewar and Zimmermann.
In this learning unit, cycloadditions, particularly the Diels-Alder reaction, are introduced as a versatile synthetic method. The stereochemistry is explained using various examples and animations.
This learning unit introduces electrocyclic reactions as a class of pericyclic reactions. Their stereochemistry and selection rules are explained in detail using various examples and animations.
In this learning unit, sigmatropic reactions are introduced as a class of pericyclic reactions. The selection rules and stereochemistry are explained in detail using various examples.
This learning unit introduces further subgroups of pericyclic reactions such as ene and retro-ene reactions, group transfer reactions, chelotropic and coartate reactions.
