- Jones oxidationOxidation The Jones oxidation is an organic reaction for the oxidation of primary and secondary alcohols to carboxylic acids and ketones, respectively.
- Julia olefinationOlefination The Julia olefination (also known as the Julia–Lythgoe olefination) is the chemical reaction used in organic chemistry of phenyl sulfones (1) with aldehydes (or ketones) to give alkenes (olefins)(3) after alcohol functionalization and reductive elimination using sodium amalgam or SmI2.
- Juliá–Colonna epoxidationOxidation The Juliá–Colonna epoxidation is an asymmetric poly-leucine catalyzed nucleophilic epoxidation of electron deficient olefins in a triphasic system.
- Kabachnik–Fields reaction In organophosphorus chemistry, the Kabachnik–Fields reaction is a three-component organic reaction forming α-aminomethylphosphonates from an amine, a carbonyl compound, and a dialkyl phosphonate, (RO)2P(O)H (that are also called dialkylphosphites).
- Kauffmann olefinationOlefination The Kauffmann olefination is a chemical reaction to convert aldehydes and ketones to olefins with a terminal methylene group.
- Keck asymmetric allylation In organic chemistry, the Keck asymmetric allylation is a chemical reaction that involves the nucleophilic addition of an allyl group to an aldehyde.
- Ketonic decarboxylation Ketonic decarboxylation (also known as decarboxylative ketonization) is a type of organic reaction involving decarboxylation, converting two equivalents of a carboxylic acid (R−C(=O)OH) to a symmetric ketone (R2C=O).
- Kharasch additionAddition The Kharasch addition is an organic reaction and a metal-catalysed free radical addition of CXCl3 compounds (X = Cl, Br, H) to alkenes.
- Kharasch–Sosnovsky reaction The Kharasch–Sosnovsky reaction is a method that involves using a copper or cobalt salt as a catalyst to oxidize olefins at the allylic position, subsequently condensing a peroxy ester (e.g. tert-Butyl peroxybenzoate) or a peroxide resulting in the formation of allylic benzoates or alcohols via radical oxidation.
- Kiliani–Fischer synthesis The Kiliani–Fischer synthesis, named for German chemists Heinrich Kiliani and Emil Fischer, is a method for synthesizing monosaccharides.
- Kinnear–Perren reaction In organophosphorus chemistry, the Kinnear–Perren reaction (sometimes the Clay-Kinnear-Perren reaction) is used to prepare alkylphosphonyl dichlorides (RP(O)Cl2) and alkylphosphonate esters (RP(O)(OR')2).
- Kirsanov reaction The Kirsanov reaction is a method for the synthesis of certain organophosphorus compounds.
- Knoevenagel condensationCondensation In organic chemistry, the Knoevenagel condensation (pronounced [ˈknøːvənaːɡl̩]) reaction is a type of chemical reaction named after German chemist Emil Knoevenagel.
- Knorr pyrrole synthesis The Knorr pyrrole synthesis is a widely used chemical reaction that synthesizes substituted pyrroles (3).
- Knorr quinoline synthesis The Knorr quinoline synthesis is an intramolecular organic reaction converting a β-ketoanilide to a 2-hydroxyquinoline using sulfuric acid.
- Koch reaction The Koch reaction is an organic reaction for the synthesis of tertiary carboxylic acids from alcohols or alkenes and carbon monoxide.
- Kochi reaction The Kochi reaction is an organic reaction for the decarboxylation of carboxylic acids to alkyl halides with lead(IV) acetate and a lithium halide.
- Koenigs–Knorr reaction The Koenigs–Knorr reaction is the substitution reaction of a glycosyl halide with an alcohol to give a glycoside.
- Kolbe electrolysis The Kolbe electrolysis or Kolbe reaction is an organic reaction named after Hermann Kolbe.
- Kolbe nitrile synthesis The Kolbe nitrile synthesis, named for Hermann Kolbe, is a method for the preparation of alkyl nitriles by reaction of the corresponding alkyl halide with a metal cyanide.
- Kolbe–Schmitt reaction The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by treating phenol with sodium hydroxide to form sodium phenoxide, then heating sodium phenoxide with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
- Kornblum oxidationOxidation The Kornblum oxidation, named after Nathan Kornblum, is an organic oxidation reaction that converts alkyl halides and tosylates into carbonyl compounds.
- Kornblum–DeLaMare rearrangementRearrangement 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.
- Kostanecki acylation The Kostanecki acylation is a method used in organic synthesis to form chromones or coumarins by acylation of O-hydroxyaryl ketones with aliphatic acid anhydrides, followed by cyclization.
