Among the following structures, which will show the most stable enamine formation?
(Where $Me$ is $- {CH}_{3}$ )

Question

Among the following structures, which will show the most stable enamine formation? (Where Me is - CH 3 )

Aicharya · Accepted Answer

All these enamines are interconvertible through their resonating structures. So most stable form is &lsquo;C&rsquo; due to steric factor. All of these has the equal resonance only differ in their geometrical configuration. The enamine in option C has bulky groups on opposite side of double bond. means they have the minimum repulsion between them.
