Meyer-Schuster rearrangement

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.Ref|Meyer1922Ref|Swaminathan1971Ref|Vartanyan1967

Acid catalysts can include acetic acid, sulfuric acid, and hydrochloric acid. Edens "et al." have investigated the reaction mechanism.Ref|Edens1977

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

Variations

Rupe rearrangement

The reaction of tertiary alcohols containing terminal acetylenic groups does not produce the expected aldehydes, but rather α,β-unsaturated methyl ketones.Ref|Rupe1926
