- Suzuki reactionCross-coupling The Suzuki reaction or Suzuki coupling is an organic reaction that uses a palladium complex catalyst to cross-couple a boronic acid to an organohalide.
- Swarts fluorination Swarts fluorination is a process whereby the chlorine atoms in a compound – generally an organic compound, but experiments have been performed using silanes – are replaced with fluorine, by treatment with antimony trifluoride in the presence of chlorine or of antimony pentachloride.
- Swern oxidationOxidation In organic chemistry, the Swern oxidation also known as Moffatt–Swern, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.
- Takai olefinationOlefination Takai olefination in organic chemistry describes the organic reaction of an aldehyde with a diorganochromium compound to form an alkene.
- Takai-Oshima-Lombardo methylenation The Takai-Oshima-Lombardo methylenation refers to reactions involving a combination of zinc, a dihalomethane, and titanium tetrachloride to perform methylenation of carbonyl derivatives.
- Thorpe reaction The Thorpe reaction is a chemical reaction described as a self-condensation of aliphatic nitriles catalyzed by base to form enamines.

- Tipson–Cohen reaction The Tipson–Cohen reaction is a name reaction first discovered by Stuart Tipson and Alex Cohen at the National Bureau of Standards in Washington D.C.
- Tishchenko reactionDisproportionationredox The Tishchenko reaction is an organic chemical reaction that involves disproportionation of an aldehyde in the presence of an alkoxide.
- Tscherniak-Einhorn reaction The Tscherniak-Einhorn reaction is an organic chemistry name reaction initiated in 1901 by Joseph Tscherniak.
- Tsuji–Trost reaction The Tsuji–Trost reaction (also called the Trost allylic alkylation or allylic alkylation) is a palladium-catalysed substitution reaction involving a substrate that contains a leaving group in an allylic position.
- Tsuji–Wilkinson decarbonylation reaction The Tsuji–Wilkinson decarbonylation reaction is a method for the decarbonylation of aldehydes and some acyl chlorides.
- Ugi reaction In organic chemistry, the Ugi reaction is a multi-component reaction involving a ketone or aldehyde, an amine, an isocyanide and a carboxylic acid to form a bis-amide.
- Ullmann condensationCondensation The Ullmann condensation or Ullmann-type reaction is the copper-promoted conversion of aryl halides to aryl ethers, aryl thioethers, aryl nitriles, and aryl amines.
- Ullmann reaction The Ullmann reaction or Ullmann coupling, named after Fritz Ullmann, couples two aryl or alkyl groups with the help of copper.
- Upjohn dihydroxylation The Upjohn dihydroxylation is an organic reaction which converts an alkene to a cis vicinal diol.
- Urech hydantoin synthesis The Urech hydantoin synthesis is the chemical reaction of amino acids with potassium cyanate and hydrochloric acid to give hydantoins.
- Van den Bergh reaction Van den Bergh reaction is a chemical reaction used to measure bilirubin levels in blood.
- Van Leusen reaction The Van Leusen reaction is the reaction of a ketone with TosMIC leading to the formation of a nitrile.
- Varrentrapp reaction The Varrentrapp reaction, also named Varrentrapp degradation, is a name reaction in the organic chemistry.
- Vicarious nucleophilic substitutionSubstitution In organic chemistry, the vicarious nucleophilic substitution is a special type of nucleophilic aromatic substitution in which a nucleophile replaces a hydrogen atom on the aromatic ring and not leaving groups such as halogen substituents which are ordinarily encountered in SNAr.
- Vilsmeier–Haack reaction The Vilsmeier–Haack reaction (also called the Vilsmeier reaction) is the chemical reaction of a substituted formamide (1) with phosphorus oxychloride and an electron-rich arene (3) to produce an aryl aldehyde or ketone (5).
- Volhard–Erdmann cyclizationCyclization The Volhard–Erdmann cyclization is an organic synthesis of alkyl and aryl thiophenes by cyclization of disodium succinate or other 1,4-difunctional compounds (γ-oxo acids, 1,4-diketones, chloroacetyl-substituted esters) with phosphorus heptasulfide.
- Von Braun amide degradation The von Braun amide degradation is the chemical reaction of a monosubstituted amide with phosphorus pentachloride or thionyl chloride to give a nitrile and an organohalide.
