Versuchsvorschrift
To a stirred, cooled (0° C.) solution of 1.0 ml (0.01625 mol) of propiolic acid in 12 ml of absolute ethanol under nitrogen was added 0.22 ml (0.0016 mol) of triethylamine. After 5 min, 1.45 ml (0.0203 mol) of thioacetic acid was added. After 20 h at 0° C. the reaction mixture was stripped of solvents to give 2.8 g of cis-3-(acetylthio)propenoic acid as a waxy solid. This product was used in the next step without further purification.
