Cyclodecyne

Cyclodecyne is a cyclic hydrocarbon with the molecular formula C10H10. It is a member of the cyclopolyyne family, which consists of hydrocarbons with alternating single and triple bonds in a cyclic structure. Cyclodecyne is characterized by its unique ring structure, which contains five triple bonds and five single bonds, resulting in a highly strained and reactive molecule.

The synthesis of cyclodecyne was first reported in 1968 by John D. Roberts and his colleagues. The compound is typically prepared through the cyclization of a linear polyyne precursor, such as 1,6-heptyne-3,5-diyne. The reaction is facilitated by the use of a strong base, such as n-butyllithium, to deprotonate the precursor and initiate the cyclization process.

Cyclodecyne exhibits a range of interesting chemical properties due to its highly strained ring structure. It is highly reactive and readily undergoes various reactions, including Diels-Alder reactions, cycloadditions, and ring-opening reactions. The compound is also known to undergo photochemical reactions, which have been studied extensively in the context of its potential use as a photochemical switch.

Despite its reactivity, cyclodecyne has found applications in various fields, including organic synthesis and materials science. Its unique structure and reactivity make it a valuable tool for the synthesis of complex organic molecules and the development of new materials with tailored properties. Ongoing research continues to explore the potential of cyclodecyne and related compounds in these and other areas.
