2. 1-Butene - Wikipedia

   en.wikipedia.org/wiki/1-Butene

   1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...

3. Butene - Wikipedia

   en.wikipedia.org/wiki/Butene

   Butene, also known as butylene, is an alkene with the formula C 4 H 8.The word butene may refer to any of the individual compounds. They are colourless gases that are present in crude oil as a minor constituent in quantities that are too small for viable extraction.

4. Ene reaction - Wikipedia

   en.wikipedia.org/wiki/Ene_reaction

   In organic chemistry, the ene reaction (also known as the Alder-ene reaction by its discoverer Kurt Alder in 1943) is a chemical reaction between an alkene with an allylic hydrogen (the ene) and a compound containing a multiple bond (the enophile), in order to form a new σ-bond with migration of the ene double bond and 1,5 hydrogen shift.

5. Zaytsev's rule - Wikipedia

   en.wikipedia.org/wiki/Zaytsev's_rule

   For example, when 2-iodobutane is treated with alcoholic potassium hydroxide (KOH), but-2-ene is the major product and but-1-ene is the minor product. [ 1 ] More generally, Zaytsev's rule predicts that in an elimination reaction the most substituted product will be the most stable, and therefore the most favored.

6. Cross-coupling reaction - Wikipedia

   en.wikipedia.org/wiki/Cross-coupling_reaction

   Cross-coupling reactions are important for the production of pharmaceuticals, [4] examples being montelukast, eletriptan, naproxen, varenicline, and resveratrol. [21] with Suzuki coupling being most widely used. [22] Some polymers and monomers are also prepared in this way. [23]

8. But-2-ene - Wikipedia

   en.wikipedia.org/wiki/But-2-ene

   But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis/trans-isomerism (also known as (E/Z)-isomerism); that is, it exists as two geometric isomers cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene). It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization ...
