- Arens–van Dorp synthesis The Arens–van Dorp synthesis is a name reaction in organic chemistry.
- Arndt–Eistert reaction In organic chemistry, the Arndt–Eistert reaction is the conversion of a carboxylic acid to its homologue.
- Asinger reaction The Asinger reaction (sometimes referred to as the Asinger-4 component reaction or A-4CR for short) is a multicomponent reaction for the synthesis of 3-thiazolines and other related heterocycles.
- Aston–Greenburg rearrangementRearrangement The Aston–Greenburg rearrangement is a name reaction in organic chemistry.
- Atherton–Todd reaction The Atherton-Todd reaction is a name reaction in organic chemistry, which goes back to the British chemists F. R. Atherton, H. T. Openshaw and A. R. Todd.
- Auwers synthesis The Auwers synthesis is a series of organic reactions forming a flavonol from a coumarone.
- Aza-Baylis–Hillman reaction The aza-Baylis–Hillman reaction or aza-BH reaction in organic chemistry is a variation of the Baylis–Hillman reaction and describes the reaction of an electron deficient alkene, usually an α,β-unsaturated carbonyl compound, with an imine in the presence of a nucleophile.
- Aza-Cope rearrangementRearrangement Rearrangements, especially those that can participate in cascade reactions, such as the aza-Cope rearrangements, are of high practical as well as conceptual importance in organic chemistry, due to their ability to quickly build structural complexity out of simple starting materials.
- Aza-Diels–Alder reaction The aza-Diels–Alder reaction is a modification of the Diels–Alder reaction wherein a nitrogen replaces sp2 carbon.
- Aza-Wittig reactionOlefination The Aza-Wittig reaction or is a chemical reaction of a carbonyl group with an aza-ylide, also known as an iminophosphorane (R3P=NR').
- Azide-alkyne Huisgen cycloadditionCycloaddition The azide-alkyne Huisgen cycloaddition is a 1,3-dipolar cycloaddition between an azide and a terminal or internal alkyne to give a 1,2,3-triazole.
- Babler oxidationOxidation The Babler oxidation, also known as the Babler–Dauben oxidation, is an organic reaction for the oxidative transposition of tertiary allylic alcohols to enones using pyridinium chlorochromate (PCC).
- Baeyer–Drewsen indigo synthesis The Baeyer–Drewsen indigo synthesis (1882) is an organic reaction in which indigo is prepared from 2-nitrobenzaldehyde and acetone The reaction was developed by von Baeyer and Viggo Drewsen in 1880 to produce the first synthetic indigo at laboratory scale.
- Baeyer–Emmerling indole synthesis Baeyer–Emmerling indole synthesis is a method for synthesizing indole from a (substituted) ortho-nitrocinnamic acid and iron powder in strongly basic solution.
- Baeyer–Villiger oxidationOxidation The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant.
- Bailey peptide synthesis The Bailey peptide synthesis is a name reaction in organic chemistry developed 1949 by J. L. Bailey.
- Baker–Venkataraman rearrangementRearrangement The Baker–Venkataraman rearrangement is the chemical reaction of 2-acetoxyacetophenones with base to form 1,3-diketones.
- Balz–Schiemann reaction The Balz–Schiemann reaction (also called the Schiemann reaction) is a chemical reaction in which an aryl diazonium salt is transformed to an aryl fluoride.
- Bamberger rearrangementRearrangement The Bamberger rearrangement is the chemical reaction of phenylhydroxylamines with strong aqueous acid, which will rearrange to give 4-aminophenols.
- Bamberger triazine synthesis The Bamberger triazine synthesis in organic chemistry is a classic organic synthesis of a triazine first reported by Eugen Bamberger in 1892.
- Bamford–Stevens reaction The Bamford–Stevens reaction is a chemical reaction whereby treatment of tosylhydrazones with strong base gives alkenes.
- Banert cascade The Banert cascade is an organic reaction in which an NH-1,2,3-triazole is prepared from a propargyl halide or sulfate and sodium azide in a dioxane- water mixture at elevated temperatures.
- Barbier reactionOrganometallic addition The Barbier reaction is an organometallic reaction between an alkyl halide (chloride, bromide, iodide), a carbonyl group and a metal.
- Barbier–Wieland degradationOrganometallic addition The Barbier–Wieland degradation is a procedure for shortening the carbon chain of a carboxylic acid by one carbon.
