Propiolaldehyde is an organic compound with molecular formula HC 2 CHO. It is the simplest chemical compound containing both alkyne and aldehyde functional groups. It is a colorless liquid with explosive properties.

Reactions

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. Its explosive properties are attributed to the exothermicity of its polymerization.

Preparation

Its acetal can be prepared from acrolein.

Occurrence in interstellar medium

Propynal has been observed in the interstellar medium. It is hypothesized to be formed from a carbon monoxide-acetylene complex. Another possible pathway is through the reaction of propynylidyne (C 3 H) with water.

Hazards

The compound is explosive, possibly because it tends to polymerize.
