- Blaise ketone synthesis The Blaise ketone synthesis (named after Edmond Blaise) is the chemical reaction of acid chlorides with organozinc compounds to give ketones.
- Blaise reaction The Blaise reaction is an organic reaction that forms a β-ketoester from the reaction of zinc metal with an α-bromoester and a nitrile.
- Blanc chloromethylation The Blanc chloromethylation (also called the Blanc reaction) is the chemical reaction of aromatic rings with formaldehyde and hydrogen chloride to form chloromethyl arenes.
- Blum–Ittah aziridine synthesis The Blum–Ittah aziridine synthesis, also known as the Blum–Ittah-Shahak aziridine synthesis or simply the Blum aziridine synthesis is a name reaction of organic chemistry, for the generation of aziridines from oxiranes.
- Bobbitt reaction The Bobbitt reaction is a name reaction in organic chemistry.
- Bodroux–Chichibabin aldehyde synthesis The Bodroux–Chichibabin aldehyde synthesis is a chemical reaction whereby a Grignard reagent is converted to an aldehyde one carbon longer.
- Boekelheide reaction The Boekelheide reaction is a rearrangement of α-picoline-N-oxides to hydroxymethylpyridines.
- Boger pyridine synthesis The Boger pyridine synthesis is a cycloaddition approach to the formation of pyridines named after its inventor Dale L. Boger, who first reported it in 1981.
- Bohlmann–Rahtz pyridine synthesis In organic chemistry, the Bohlmann–Rahtz pyridine synthesis is a reaction that generates substituted pyridines in two steps, first a condensation reaction between an enamine and an ethynylketone to form an aminodiene intermediate, which after heat-induced E/Z isomerization undergoes a cyclodehydration to yield 2,3,6-trisubstituted pyridines.
- Bohn–Schmidt reactionRearrangement The Bohn–Schmidt reaction, a named reaction in chemistry, introduces a hydroxy group at an anthraquinone system.
- Boord olefin synthesis The Boord olefin synthesis is an organic reaction forming alkenes from ethers carrying a halogen atom 2 carbons removed from the oxygen atom (β-halo-ethers) using a metal such as magnesium or zinc.
- Borsche–Drechsel cyclizationCyclization The Borsche–Drechsel cyclization is a chemical reaction used to synthesize tetrahydrocarbazoles by the acid-catalyzed cyclization of cyclohexanone arylhydrazones.
- Bosch reaction The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO2) and hydrogen (H2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat.
- Boudouard reaction The Boudouard reaction, named after Octave Leopold Boudouard, is the redox reaction of a chemical equilibrium mixture of carbon monoxide and carbon dioxide at a given temperature.
- Bouveault aldehyde synthesis The Bouveault aldehyde synthesis (also known as the Bouveault reaction) is a one-pot substitution reaction that replaces an alkyl or aryl halide with a formyl group using a N,N-disubstituted formamide.
- Bouveault–Blanc reductionReduction The Bouveault–Blanc reduction is a chemical reaction in which an ester is reduced to primary alcohols using absolute ethanol and sodium metal.
- Boyland–Sims oxidationOxidation The Boyland–Sims oxidation is the chemical reaction of anilines with alkaline potassium persulfate, which after hydrolysis forms ortho-hydroxyl anilines.
- Bradsher cycloadditionCycloaddition The Bradsher cycloaddition reaction, also known as the Bradsher cyclization reaction is a form of the Diels–Alder reaction which involves the [4+2] addition of a common dienophile with a cationic aromatic azadiene such as acridizinium or isoquinolinium.
- Bray–Liebhafsky reaction The Bray–Liebhafsky reaction is a chemical clock first described by William C. Bray in 1921 and the first oscillating reaction in a stirred homogeneous solution.
- Briggs–Rauscher reaction The Briggs–Rauscher oscillating reaction is one of a small number of known oscillating chemical reactions.
- Brook rearrangementRearrangement In organic chemistry the Brook rearrangement refers to any [1,n] carbon to oxygen silyl migration.
- Bruylants reaction In organic chemistry, the Bruylants reaction (sometimes misspelled Bruylant) is a substitution reaction in which a Grignard reagent replaces a nitrile on a carbon that also has an amino group (c.f. cyanohydrin).
- Bucherer carbazole synthesis The Bucherer carbazole synthesis is a chemical reaction used to synthesize carbazoles from 2-naphthols and aryl hydrazines using sodium bisulfite.
