- De Kimpe aziridine synthesis The De Kimpe aziridine synthesis is a name reaction of organic chemistry, for the generation of aziridines by the reaction of α-chloroimines with nucleophiles such as hydride, cyanide, or Grignard reagents.
- Debus–Radziszewski imidazole synthesis The Debus–Radziszewski imidazole synthesis is a multi-component reaction used for the synthesis of imidazoles from a 1,2-dicarbonyl, an aldehyde, and ammonia or a primary amine.
- Delépine reaction The Delépine reaction is the organic synthesis of primary amines (4) by reaction of benzyl or alkyl halides (1) with hexamethylenetetramine (2) followed by acid hydrolysis of the quaternary ammonium salt (3).
- DeMayo reaction The DeMayo reaction or Ciamician-DeMayo reaction is a photochemical reaction in which the enol of a 1,3-diketone reacts with an alkene (or another species with a C=C bond) and the resulting cyclobutane ring undergoes a retro-aldol reaction to yield a 1,5-diketone.

- Dimroth rearrangementRearrangement The Dimroth rearrangement is a rearrangement reaction taking place with certain 1,2,3-triazoles where endocyclic and exocyclic nitrogen atoms switch place.
- Doebner reaction The Doebner reaction is the chemical reaction of an aniline with an aldehyde and pyruvic acid to form quinoline-4-carboxylic acids.
- Doebner–Miller reaction The Doebner–Miller reaction is the organic reaction of an aniline with α,β-unsaturated carbonyl compounds to form quinolines.
- Doering–LaFlamme allene synthesis The Doering–LaFlamme allene synthesis is a reaction of alkenes that converts them to allenes by insertion of a carbon atom.
- Dowd–Beckwith ring-expansion reaction The Dowd–Beckwith ring-expansion reaction is an organic reaction in which a cyclic carbonyl (typically a β-keto ester) is expanded by up to 4 carbons in a free radical ring expansion reaction through an α-alkylhalo substituent.
- Doyle–Kirmse reaction The Doyle–Kirmse reaction is an organic reaction in which a metal carbene reacts with an allyl compound with transposition of the alkene and transfer of the electronegative group from the allyl onto the carbene carbon.
