Exempel på hur man kan använda CYCLOPROPENE i en mening

• Monocyclic cycloalkenes are cyclopropene, cyclobutene, cyclopentene, cyclohexene, cycloheptene, cyclooctene, and so on.
• Later Schlatter improved the pyrolytic reaction conditions using platinized asbestos as a catalyst at 320–330 °C and obtained cyclopropene in 45% yield.
• It is an example of a cross-conjugated alkene, being composed of cyclopropene with an exocyclic double bond attached.
• Cycloalkanes generally have less ring strain than cycloalkenes, which is seen when comparing cyclopropane and cyclopropene.
• The chemical properties of diphenylcyclopropenone are dominated by the strong polarization of the carbonyl group, which gives a partial positive charge with aromatic stabilization on the cyclopropene (cyclopropenium) ring and a partial negative charge on oxygen.
• Sterculia foetida oil contains cyclopropene fatty acids (CPFA) such as 8,9 methylene-heptadec-8-enoic acid (malvalic acid) and 9,10-methylene-ocadec-9-enoic acid (sterculic acid).
• The product, dihydrosterculic acid, is converted to sterculic acid by dehydrogenation of the cis-disubstituted cyclopropane to cyclopropene.
• Upon addition of the zirconocene bis(trimethylsilyl) acetylene pyridine to cyclopropyl methyl ketone, a zirconium oxygen bond formed simultaneously forming a new carbon-carbon bond from the cyclopropene and the carbonyl carbon.
