As the reaction proceeds, 6 pi electrons are delocalized above the transition state, which stabilizes it by the Hammond Postulate. Thus, these reactions have a faster rate and are more stable than two plus two and four plus four cycloaddition reactions. Most of the reactions
As the reaction proceeds, 6 pi electrons are delocalized above the transition state, which stabilizes it by the Hammond Postulate. Thus, these reactions have a faster rate and are more stable than two plus two and four plus four cycloaddition reactions. Most of the reactions are not reversible, however under a large amount of heat the retro reaction proceeds. The discovers, working at the University of Cologne, shared the Nobel Prize in Chemistry in 1950 for the discovery of the reaction between a substituted alkene and a conjugated diene. This is, for ten points, which class of reactions that results in a cyclic alkene?
