Enyne
{{short description|1=Any organic compound containing a C=C and C≡C bond}}
An enyne is an organic compound containing a {{chem2|C\dC}} double bond (alkene) and a {{chem2|C\tC}} triple bond (alkyne).{{cite web|title=Basic IUPAC Organic Nomenclature: Enynes|url=http://www.chem.ucalgary.ca/courses/350/orgnom/alkynes/alkynes-03.html|website=University of Calgary|publisher=chem.ucalgary.ca|access-date=18 May 2017}} It is called a conjugated enyne when the double and triple bonds are conjugated.
The term is a contraction of the terms alkene and alkyne.
The simplest enyne is vinylacetylene.{{Cite journal |last1=Monnier |first1=Florian |last2=Vovard-Le Bray |first2=Chloé |last3=Castillo |first3=Dante |last4=Aubert |first4=Vincent |last5=Dérien |first5=Sylvie |last6=Dixneuf |first6=Pierre H. |last7=Toupet |first7=Loic |last8=Ienco |first8=Andrea |last9=Mealli |first9=Carlo |date=2007-04-13 |title=Selective Ruthenium-Catalyzed Transformations of Enynes with Diazoalkanes into Alkenylbicyclo[3.1.0]hexanes |url=http://dx.doi.org/10.1021/ja0700146 |journal=Journal of the American Chemical Society |volume=129 |issue=18 |pages=6037–6049 |doi=10.1021/ja0700146 |pmid=17429974 |issn=0002-7863|url-access=subscription }}
The organic enynes are isanolic acid and exocarpic acid.
