  2. Alkene - Wikipedia

    en.wikipedia.org/wiki/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. The International Union of Pure and Applied Chemistry (IUPAC) recommends using the name "alkene" only for acyclic hydrocarbons ...

  3. Hydroformylation - Wikipedia

    en.wikipedia.org/wiki/Hydroformylation

    In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R2C=CR2). [1][2] This chemical reaction entails the net addition of a formyl group (−CHO) and a hydrogen atom to a carbon-carbon double bond. This process has undergone ...

  4. Aldol condensation - Wikipedia

    en.wikipedia.org/wiki/Aldol_condensation

    Aldol condensation. An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone. The overall reaction equation is as follows (where the ...

  5. Baylis–Hillman reaction - Wikipedia

    en.wikipedia.org/wiki/Baylis–Hillman_reaction

    In organic chemistry, the Baylis–Hillman, Morita–Baylis–Hillman, or MBH reaction is a carbon-carbon bond-forming reaction between an activated alkene and a carbon electrophile in the presence of a nucleophilic catalyst, such as a tertiary amine or phosphine. The product is densely functionalized, joining the alkene at the α-position to a ...

  6. Heck reaction - Wikipedia

    en.wikipedia.org/wiki/Heck_reaction

    heck-reaction. RSC ontology ID. RXNO:0000024. The Heck reaction (also called the Mizoroki–Heck reaction) [1] is the chemical reaction of an unsaturated halide (or triflate) with an alkene in the presence of a base and a palladium catalyst to form a substituted alkene.

  7. Terminal alkene - Wikipedia

    en.wikipedia.org/wiki/Terminal_alkene

    The double bond of an alpha olefin is between the #1 and #2 (IUPAC) or α and β (common) carbon atoms. 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 CxH2x, distinguished by having a double bond at the primary ...

  8. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    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 ...

  9. Dehydrogenation - Wikipedia

    en.wikipedia.org/wiki/Dehydrogenation

    Dehydrogenation. In chemistry, dehydrogenation is a chemical reaction that involves the removal of hydrogen, usually from an organic molecule. It is the reverse of hydrogenation. Dehydrogenation is important, both as a useful reaction and a serious problem. At its simplest, it's a useful way of converting alkanes, which are relatively inert and ...
