Figure 7.4. Kinetic and Thermodynamic Enolates The kinetic enolate forms more quickly, but is less stable than the thermodynamic enolate.

Each of these two products is favored by different conditions. The kinetic product is favored in reactions that are rapid, irreversible, at lower temperatures, and with a strong, sterically hindered base. If the reaction is reversible, the kinetic product can revert to the original reactant and react again to form the thermodynamic product. The thermodynamic product is favored with higher temperatures; slow, reversible reactions; and weaker, smaller bases.
