- Mannich reactionAddition In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of the α-position of a ketone or aldehyde with an aldehyde and a nullary, primary, or secondary amine (−NH2).
- Marker degradation The Marker degradation is a three-step synthetic route in steroid chemistry developed by American chemist Russell Earl Marker in 1938–1940.
- Markó–Lam deoxygenation The Markó–Lam deoxygenation is an organic chemistry reaction where the hydroxy functional group in an organic compound is replaced by a hydrogen atom to give an alkyl group.
- Marschalk reaction The Marschalk reaction in chemistry is the sodium dithionite promoted reaction of a phenolic anthraquinone with an aldehyde to yield a substituted phenolic anthraquinone after the addition of acid.
- Marsh test The Marsh test is a highly sensitive method in the detection of arsenic, especially useful in the field of forensic toxicology when arsenic was used as a poison.
- Martinet dioxindole synthesis The Martinet dioxindole synthesis was first reported in 1913 by J. Martinet.
- McCormack reaction The McCormack reaction is a method for the synthesis of organophosphorus compounds.
- McFadyen–Stevens reaction The McFadyen–Stevens reaction is a chemical reaction best described as a base-catalyzed thermal decomposition of acylsulfonylhydrazides to aldehydes.
- McLafferty rearrangementRearrangement The McLafferty rearrangement is a fragmentation reaction observed in mass spectrometry of organic molecules in which the parent radical cation splits into daughter radical cation and neutral spin-paired molecule.
- McMurry reaction The McMurry reaction is an organic reaction in which two ketone or aldehyde groups are coupled to form an alkene using a titanium chloride compound such as titanium(III) chloride and a reducing agent.
- Meerwein arylation The Meerwein arylation is an organic reaction involving the addition of an aryl diazonium salt (ArN2X) to an electron-poor alkene usually supported by a metal salt.
- Meerwein–Ponndorf–Verley reductionReduction The Meerwein–Ponndorf–Verley (MPV) reduction in organic chemistry is the reduction of ketones and aldehydes to their corresponding alcohols utilizing aluminium alkoxide catalysis in the presence of a sacrificial alcohol.
- Meisenheimer rearrangementRearrangement In organic chemistry, the Meisenheimer rearrangement is the conversion of a tertiary amine oxide to a alkoxylamine.
- Menke nitration The Menke nitration is the nitration of electron rich aromatic compounds with cupric nitrate and acetic anhydride.
- Menshutkin reaction In organic chemistry, the Menshutkin reaction converts a tertiary amine into a quaternary ammonium salt by reaction with an alkyl halide.
- Meyer–Schuster rearrangementRearrangement The Meyer–Schuster rearrangement is the chemical reaction described as an acid-catalyzed rearrangement of secondary and tertiary propargyl alcohols to α,β-unsaturated ketones if the alkyne group is internal and α,β-unsaturated aldehydes if the alkyne group is terminal.
- Meyers synthesis The Meyers synthesis is an organic synthesis for the preparation of unsymmetrical aldehydes via hydrolysis of an oxazine.
- Michael addition reactionAddition In organic chemistry, the Michael reaction or Michael 1,4 addition is a reaction between a Michael donor (an enolate or other nucleophile) and a Michael acceptor (usually an α,β-unsaturated carbonyl) to produce a Michael adduct by creating a carbon-carbon bond at the acceptor's β-carbon.
- Michaelis–Arbuzov reactionAddition The Michaelis–Arbuzov reaction (also called the Arbuzov reaction) is the chemical reaction of a trivalent phosphorus ester with an alkyl halide to form a pentavalent phosphorus species and another alkyl halide.
- Michaelis–Becker reactionAddition The Michaelis–Becker reaction is the reaction of a hydrogen (thio)phosphonate with a base, followed by a nucleophilic substitution of phosphorus on a haloalkane, to give an alkyl (thio)phosphonate.
- Milas hydroxylation The Milas hydroxylation is an organic reaction converting an alkene to a vicinal diol, and was developed by Nicholas A. Milas in the 1930s.
- Minisci reaction The Minisci reaction (Italian: [miˈniʃʃi]) is a named reaction in organic chemistry.
- Mislow–Evans rearrangementRearrangement The Mislow–Evans rearrangement is a name reaction in organic chemistry.
- Mitsunobu reactionSubstitution The Mitsunobu reaction is an organic reaction that converts an alcohol into a variety of functional groups, such as an ester, using triphenylphosphine and an azodicarboxylate such as diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate (DIAD).
