Kowalski ester homologation



The Kowalski ester homologation is a chemical reaction for the homologation of esters.[1][2]

This reaction was designed as a safer alternative to the Arndt-Eistert synthesis. The Kowalski reaction is named after its inventor, Conrad J. Kowalski.

Additional recommended knowledge

Reaction mechanism

The mechanism is disputed.

Variations

A modification of the procedure has been described that results in higher yields.[3]

By changing the reagent in the second step of the reaction, the Kowalski ester homologation can also be used for the preparation of silyl ynol ethers.[citation needed]
