Pericyclic Reactions

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.
