Chemical compound

1-Butyne is an organic compound with the formula CH3CH2C≡CH. It is a terminal alkyne. The compound is a common terminal alkyne substrate in diverse studies of catalysis. It is a colorless combustible gas.[1]

1-Butyne participates in reactions typical for terminal alkynes, such as alkyne metathesis,[2] hydrogenation, condensation with formaldehyde. Based on its heat of combustion, it is slightly more stable than its isomer 2-butyne.[3]
