Chemical compound
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.
01Reactions
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.
02Preparation
Its acetal can be prepared from acrolein.
03Occurrence 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 (C3H) with water.
04Hazards
The compound is explosive, possibly because it tends to polymerize.
