Question

What is the reason for only one enolate forming predominantly in a typical Claisen-Schmidt reaction?

Accepted Answer

The base used selectively deprotonates the most acidic alpha hydrogen.

Answer

The presence of water shifts the equilibrium towards one enolate.

Answer

Only the aldehyde can form an enolate in the reaction conditions.

Answer

The reaction is carried out at a low temperature, which favors one enolate.
