  2. Formylation - Wikipedia

    en.wikipedia.org/wiki/Formylation

    Hydroformylation of alkenes is the most important method for obtaining aliphatic formyls (i.e., aldehydes). The reaction is largely restricted to industrial settings. Several specialty methods exist for laboratory-scale synthesis, including the Sommelet reaction, Bouveault aldehyde synthesis or Bodroux–Chichibabin aldehyde synthesis.

  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. Enol - Wikipedia

    en.wikipedia.org/wiki/Enol

    In organic chemistry, enols are a type of Functional group or intermediate in organic chemistry containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a portmanteau deriving from "-ene"/"alkene" and the "-ol". Many kinds of enols are known. [1]

  5. Rearrangement reaction - Wikipedia

    en.wikipedia.org/wiki/Rearrangement_reaction

    In organic chemistry, a rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. [1] Often a substituent moves from one atom to another atom in the same molecule, hence these reactions are usually intramolecular. In the example below ...

  6. Enol ether - Wikipedia

    en.wikipedia.org/wiki/Enol_ether

    In organic chemistry an enol ether is an alkene with an alkoxy substituent. [1] The general structure is R 2 C=CR-OR where R = H, alkyl or aryl. A common subfamily of enol ethers are vinyl ethers, with the formula ROCH=CH 2. Important enol ethers include the reagent 3,4-dihydropyran and the monomers methyl vinyl ether and ethyl vinyl ether.

  7. Haloform reaction - Wikipedia

    en.wikipedia.org/wiki/Haloform_reaction

    In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.

  8. Shapiro reaction - Wikipedia

    en.wikipedia.org/wiki/Shapiro_reaction

    The Shapiro reaction or tosylhydrazone decomposition is an organic reaction in which a ketone or aldehyde is converted to an alkene through an intermediate hydrazone in the presence of 2 equivalents of organolithium reagent. [1] [2] [3] The reaction was discovered by Robert H. Shapiro in 1967. [4]

  9. Prins reaction - Wikipedia

    en.wikipedia.org/wiki/Prins_reaction

    The Prins reaction is an organic reaction consisting of an electrophilic addition of an aldehyde or ketone to an alkene or alkyne followed by capture of a nucleophile or elimination of an H + ion. [ 1 ] [ 2 ] [ 3 ] The outcome of the reaction depends on reaction conditions.
