Application

2-Butynoic acid was employed as synthon in a variety of reactions, including cycloacylation of phenols to flavones and chromones, and cyclization to γ-butyrolactones. It was also used in synthesis of Z-trisubstituted olefins via γ-alkylation.

General description

The rotational spectrum of 2-butynoic acid was measured by pulsed supersonic-jet Fourier transform microwave spectroscopy.
