Cyclopropyne is an extremely strained, unstable, and reactive cycloalkyne with the chemical formula C3H2.[1][2] As the smallest cycloalkyne, it features a three-carbon ring that includes a triple bond. The significant ring strain makes the compound challenging to produce and causes its high reactivity.[3]

Theoretical studies

[edit]

Although cyclopropyne is inherently unstable, it has been extensively investigated through theoretical studies aimed at exploring its electronic structure, energy properties, and vibrational characteristics. A similar compound called silacyclopropyne, in which a silicon atom substitutes one of the carbon atoms in the ring, has been successfully synthesized and examined.[4]
