Pericyclic Reactions

  • Robert B. Grossman


A pericyclic reaction is a reaction in which bonds are formed or broken at the termini of one or more conjugated π systems. The electrons move around in a circle, all bonds are made and broken simultaneously, and no intermediates intervene. The requirement of concertedness distinguishes pericyclic reactions from most polar or free-radical reactions, although for many pericyclic reactions reasonable alternative stepwise mechanisms can also be drawn.
