  2. Syn and anti addition - Wikipedia

    en.wikipedia.org/wiki/Syn_and_anti_addition

    In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.

  3. α,β-Unsaturated carbonyl compound - Wikipedia

    en.wikipedia.org/wiki/Α,β-Unsaturated_carbonyl...

    An enal (or alkenal) is an organic compound containing both alkene and aldehyde functional groups. In an α,β-unsaturated enal, the alkene is conjugated to the carbonyl group of the aldehyde (formyl group). [3] The simplest enal is acrolein (CH 2 =CHCHO). Other examples include cis-3-hexenal (essence of mowed lawns) and cinnamaldehyde (essence ...

  4. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    A 3D model of ethylene, the simplest alkene. In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. [1] The double bond may be internal or in the terminal position. Terminal alkenes are also known as α-olefins.

  5. Addition reaction - Wikipedia

    en.wikipedia.org/wiki/Addition_reaction

    In organic chemistry, an addition reaction is an organic reaction in which two or more molecules combine to form a larger molecule called the adduct. [1] [2] An addition reaction is limited to chemical compounds that have multiple bonds. Examples include a molecule with a carbon–carbon double bond (an alkene) or a triple bond (an alkyne).

  6. Ozonolysis - Wikipedia

    en.wikipedia.org/wiki/Ozonolysis

    In organic chemistry, ozonolysis is an organic reaction where the unsaturated bonds are cleaved with ozone (O 3). Multiple carbon–carbon bond are replaced by carbonyl (C=O) groups, such as aldehydes, ketones, and carboxylic acids. The reaction is predominantly applied to alkenes, but alkynes and azo compounds are also susceptible to cleavage.

  7. Terminal alkene - Wikipedia

    en.wikipedia.org/wiki/Terminal_alkene

    In organic chemistry, terminal alkenes (alpha-olefins, α-olefins, or 1-alkenes) are a family of organic compounds which are alkenes (also known as olefins) with a chemical formula C x H 2x, distinguished by having a double bond at the primary, alpha (α), or 1-position. [1]

  8. Doering–LaFlamme allene synthesis - Wikipedia

    en.wikipedia.org/wiki/Doering–LaFlamme_allene...

    The reaction is a two-stage process, in which first the alkene is reacted with dichlorocarbene or dibromocarbene to form a dihalocyclopropane. This intermediate is then reacted with a reducing metal, such as sodium or magnesium, or with an organolithium reagent .

  9. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. [ 1 ] [ 2 ] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative ...
