Propiolaldehyde is an organic compound with molecular formula HC2CHO. It is the simplest chemical compound containing both alkyne and aldehyde functional groups. It is a colorless liquid with explosive properties. [1]
The compound exhibits reactions expected for an electrophilic alkynyl aldehyde. It is a dienophile and a good Michael acceptor. Grignard reagents add to the carbonyl center. [1] Its explosive properties are attributed to the exothermicity of its polymerization. [1]
Its acetal can be prepared from acrolein. [2]
Propynal has been observed in the interstellar medium. It is hypothesized to be formed from a carbon monoxide- acetylene complex. [3] Another possible pathway is through the reaction of propynylidyne (C3H) with water. [4]
The compound is explosive, possibly because it tends to polymerize. [1]
