Acetic Acids

Substituted acetic acids can be prepared in good yield (50–80%) from terminal acetylenes of the same chain length. The alkyne is first converted to the thiophenyl ether, which is treated without purification with mercuric sulfate in acetic acid and 2 N sulfuric acid affording the carboxylic acid. The method is particularly useful in the synthesis of long chain ω-hydroxyalkanoic acids.
