alkene's Usage Examples:

Aliphatic compounds can be saturated, joined by single bonds (alkanes), or unsaturated, with double bonds (alkenes) or triple bonds (alkynes).

A second one-electron transfer leads to the anion, which also abstracts a proton to the neutral alkene.

Polyketones, thermoplastic polymers, are formed by the copolymerisation of carbon monoxide and one or more alkenes (typically ethylene with.

ReactionsThe main areas of use are the conversion of ketones to esters (Baeyer-Villiger oxidation), epoxidation of alkenes (Prilezhaev reaction), conversion of silyl enol ethers to silyl α-hydroxy ketones (Rubottom oxidation), oxidation of sulfides to sulfoxides and sulfones, and oxidation of amines to produce amine oxides.

With unsymmetrical alkenes or alkynes, regioselectivity can be problematic, but less so.

Singlet carbenes add stereospecifically to alkenes, and alkene stereochemistry is retained in the cyclopropane product.

the Grignard reaction, converting it to an alkene by dehydration, and hydrogenating the latter.

de/Mountains of BavariaAllgäu AlpsMountains of the Alps The Bamford–Stevens reaction is a chemical reaction whereby treatment of tosylhydrazones with strong base gives alkenes.

Generally the substrate will be an alkene or alkyne.

These occur between alkenes and electrophiles, often halogens as in halogen addition reactions.

Angle strain also is the basis of Bredt's rule which dictates that bridgehead carbon centers are not incorporated in alkenes because the resulting alkene would be subject to extreme angle strain.

The direct hydration using ethylene (ethylene hydration) or other alkenes from cracking of fractions of distilled crude oil.

The Boord olefin synthesis is an organic reaction forming alkenes from ethers carrying a halogen atom 2 carbons removed from the oxygen atom (β-halo-ethers).
