colourless to light yellow liquid
Methyl propiolate was used in the synthesis of polysubstituted 3-arylaminoacrylate and tetrahydropyrimidin-2-one derivatives. It was also used as a thiol derivatizing agent for capillary electrophoresis.
Methyl Propiolate is an α,β-unsaturated ester that can undergo Diels-Alder and various other cycloaddition reactions, Michael additions, acetylide formation, halogen addition, as well as a range of cyclization reactions to produce heterocycles and aromatic compounds.
methyl and ethyl propiolate are lachrymatory liquids; handle in a well-ventilated fume hood.
Purify the propiolate by fractional distillation and collecting the middle fraction, note that propiolic acid has a high b [144o(dec)/760mm]. [Beilstein 2 IV 1688.] LACHRYMATORY.
