Chapter 20, Problem 29P(choose chapter or problem)
A tertiary amine reacts with hydrogen peroxide to form a tertiary amine oxide.
Tertiary amine oxides undergo a reaction similar to the Hofmann elimination reaction ( Section \(11.10\) ) , called a Cope elimination.
In this reaction, a tertiary amine oxide, rather than a quaternary ammonium ion, undergoes elimination. A strong base is not needed for a Cope elimination because the amine oxide acts as its own base.
Does the Cope elimination have an alkene-like transition state or a carbanion-like transition state?
