- Kowalski ester homologation The Kowalski ester homologation is a chemical reaction for the homologation of esters.
- Krapcho decarboxylation Krapcho decarboxylation is a chemical reaction used to manipulate certain organic esters.
- Kröhnke pyridine synthesis Kröhnke pyridine synthesis is a reaction in organic synthesis that occurs between α-pyridinium methyl ketone salts and α, β-unsaturated carbonyl compounds and is used to generate highly functionalized pyridines.
- Kulinkovich reaction The Kulinkovich reaction describes the organic synthesis of substituted cyclopropanols through reaction of esters with dialkyldialkoxytitanium reagents, which are generated in situ from Grignard reagents containing a hydrogen in beta-position and titanium(IV) alkoxides such as titanium isopropoxide.
- Kumada couplingCross-coupling In organic chemistry, the Kumada coupling is a type of cross coupling reaction, useful for generating carbon–carbon bonds by the reaction of a Grignard reagent and an organic halide.
- Larock indole synthesis The Larock indole synthesis is a heteroannulation reaction that uses palladium as a catalyst to synthesize indoles from an ortho-iodoaniline and a disubstituted alkyne.
- Leblanc process The Leblanc process was an early industrial process for making soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.
- Lehmstedt–Tanasescu reaction The Lehmstedt–Tanasescu reaction is a method in organic chemistry for the organic synthesis of acridone derivatives (3) from a 2-nitrobenzaldehyde (1) and an arene compound (2).
- Leimgruber–Batcho indole synthesis The Leimgruber–Batcho indole synthesis is a series of organic reactions that produce indoles from o-nitrotoluenes 1.
- Lemieux–Johnson oxidationOxidation The Lemieux–Johnson or Malaprade–Lemieux–Johnson oxidation is a chemical reaction in which an olefin undergoes oxidative cleavage to form two aldehyde or ketone units.
- Letts nitrile synthesis The Letts nitrile synthesis is a chemical reaction of aromatic carboxylic acids with metal thiocyanates to form nitriles.
- Leuckart reaction The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines.
- Leuckart thiophenol reaction The Leuckart thiophenol reaction is the decomposition of a diazoxanthate, by gentle warming in a slightly acidic cuprous medium, to its corresponding aryl xanthates which give aryl thiols on alkaline hydrolysis and aryl thioethers on further warming.
- Liebeskind–Srogl couplingCross-coupling The Liebeskind–Srogl coupling reaction is an organic reaction forming a new carbon–carbon bond from a thioester and a boronic acid using a metal catalyst.
- Lindgren oxidationOxidation Lindgren oxidation is a selective method for oxidizing aldehydes to carboxylic acids.
- Lobry de Bruyn–Van Ekenstein transformation 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.
- Lombardo methylenation In organic chemistry, the Lombardo methylenation is a name reaction that allows for the methylenation of carbonyl compounds with the use of Lombardo's reagent, which is a mix of zinc, dibromomethane, and titanium tetrachloride.
- Lossen rearrangementRearrangement The Lossen rearrangement is the conversion of an acyl hydroxamate to an isocyanate and carboxylic acid side product.
- Luche reductionReduction Luche reduction is the selective organic reduction of α,β-unsaturated ketones to allylic alcohols.
- Lumière–Barbier methodOrganometallic addition The Lumière–Barbier method is a method of acetylating aromatic amines in aqueous solutions.
- Madelung synthesis In organic chemistry, Madelung synthesis is a chemical reaction that produces (substituted or unsubstituted) indoles by the intramolecular cyclization of N-phenylamides using strong base at high temperature.
- Maillard reaction The Maillard reaction (MY-ar; French: [majaʁ]) is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds that give browned food its distinctive flavor.
- Malaprade reaction In organic chemistry, the Malaprade reaction or Malaprade oxidation is a reaction that converts vicinal diols by periodic acid or a periodate salt to give a pair of carbonyl derivatives.
- Mallory reaction In organic chemistry, the Mallory reaction is a photochemical-cyclization–elimination reaction of diaryl-ethylene structures to form phenanthrenes and other polycyclic form polycyclic aromatic hydrocarbons and heteroaromatics.
