  2. Ketone halogenation - Wikipedia

    en.wikipedia.org/wiki/Ketone_halogenation

    The position alpha to the carbonyl group (C=O) in a ketone is easily halogenated. This is due to its ability to form an enolate (C=C−O −) in basic solution, or an enol (C=C−OH) in acidic solution. An example of alpha halogenation is the mono-bromination of acetone ((CH 3) 2 C=O), carried out under either acidic or basic conditions, to ...

  3. Carbonyl α-substitution reaction - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_α-substitution...

    Remarkably, ketone halogenation also occurs in biological systems, particularly in marine algae, where dibromoacetaldehyde, bromoacetone, 1, l,l -tribromoacetone, and other related compounds have been found. The halogenation is a typical α-substitution reaction that proceeds by acid catalyzed formation of an enol intermediate. [1]: 846

  4. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.

  5. Corey–Kim oxidation - Wikipedia

    en.wikipedia.org/wiki/Corey–Kim_oxidation

    Dimethyl sulfide (Me 2 S) is treated with N-chlorosuccinimide (NCS), resulting in formation of an "active DMSO" species that is used for the activation of the alcohol. Addition of triethylamine to the activated alcohol leads to its oxidation to aldehyde or ketone and generation of dimethyl sulfide. In variance with other alcohol oxidation using ...

  6. Friedel–Crafts reaction - Wikipedia

    en.wikipedia.org/wiki/Friedel–Crafts_reaction

    A typical Lewis acid catalyst is aluminium trichloride. Because, however, the product ketone forms a rather stable complex with Lewis acids such as AlCl 3, a stoichiometric amount or more of the "catalyst" must generally be employed, unlike the case of the Friedel–Crafts alkylation, in which the catalyst is constantly regenerated. [13]

  7. Kornblum–DeLaMare rearrangement - Wikipedia

    en.wikipedia.org/wiki/Kornblum–DeLaMare...

    The Kornblum–DeLaMare rearrangement is a rearrangement reaction in organic chemistry in which a primary or secondary organic peroxide is converted to the corresponding ketone and alcohol under acid or base catalysis. The reaction is relevant as a tool in organic synthesis and is a key step in the biosynthesis of prostaglandins. [1]

  8. Lobry de Bruyn–Van Ekenstein transformation - Wikipedia

    en.wikipedia.org/wiki/Lobry_de_Bruyn–van...

    In carbohydrate chemistry, the Lobry de Bruyn–Van Ekenstein transformation also known as the Lobry de Bruyn–Alberda van Ekenstein transformation is the base or acid catalyzed transformation of an aldose into the ketose isomer or vice versa, with a tautomeric enediol as reaction intermediate. Ketoses may be transformed into 3-ketoses, etcetera.

  9. Carbonyl reduction - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_reduction

    In organic chemistry, carbonyl reduction is the conversion of any carbonyl group, usually to an alcohol. It is a common transformation that is practiced in many ways. [1] Ketones, aldehydes, carboxylic acids, esters, amides, and acid halides - some of the most pervasive functional groups, -comprise carbonyl compounds.
