Meyer-Schuster rearrangement

The Meyer-Schuster rearrangement is the chemical reaction described as an acid-catalyzed rearrangement of propargyl alcohols to α,β-unsaturated ketones.



Acid catalysts can include acetic acid, sulfuric acid, and hydrochloric acid. Edens et al. have investigated the reaction mechanism.

When catalyzed by base, the reaction is called the Favorskii reaction.

Rupe rearrangement
The reaction of tertiary alcohols containing terminal acetylenic groups does not produce the expected aldehydes, but rather α,β-unsaturated methyl ketones.
