Group transfer reactions are pericyclic reactions where one pi bond is converted to one sigma bond, at the same time that a sigma bond migrates. In Organic chemistry, a pericyclic reaction is a type of Organic reaction wherein the Transition state of the molecule has a cyclic geometry and the reaction
The best known group transfer reaction is the ene reaction. The Ene reaction (also known as the Alder-ene reaction) is a Chemical reaction between an Alkene with an Allylic Hydrogen (the
