- Prato reaction The Prato reaction is a particular example of the well-known 1,3-dipolar cycloaddition of azomethine ylides to olefins.
- Prévost reaction The Prévost reaction is a chemical reaction in which an alkene is converted by iodine and the silver salt of benzoic acid to a vicinal diol with anti stereochemistry.
- Prilezhaev reaction The Prilezhaev reaction, also known as the Prileschajew reaction or Prilezhaev epoxidation, is the chemical reaction of an alkene with a peroxy acid to form epoxides.
- Prins reaction The Prins reaction is an organic reaction consisting of an electrophilic addition of an aldehyde or ketone to an alkene or alkyne followed by capture of a nucleophile or elimination of an H+ ion.
- Pschorr cyclizationCyclization The Pschorr cyclization is a name reaction in organic chemistry, which was named after its discoverer, the German chemist Robert Pschorr (1868-1930).
- Pudovik reaction In organophosphorus chemistry, the Pudovik reaction is a method for preparing α-aminomethylphosphonates.
- Pummerer rearrangementRearrangement The Pummerer rearrangement is an organic reaction whereby an alkyl sulfoxide rearranges to an α-acyloxy–thioether (monothioacetal-ester) in the presence of acetic anhydride.
- Quelet reaction The Quelet reaction (also called the Blanc–Quelet reaction) is an organic coupling reaction in which a phenolic ether reacts with an aliphatic aldehyde to generate an α-chloroalkyl derivative.
- Ramberg–Bäcklund reaction The Ramberg–Bäcklund reaction is an organic reaction converting an α-halo sulfone into an alkene in presence of a base with extrusion of sulfur dioxide.
- Rauhut–Currier reaction The Rauhut–Currier reaction, also called the vinylogous Morita–Baylis–Hillman reaction, is an organic reaction describing (in its original scope) the dimerization or isomerization of electron-deficient alkenes such as enones by action of an organophosphine of the type R3P.
- Reed reaction The Reed reaction is a chemical reaction that utilizes light to oxidize hydrocarbons to alkylsulfonyl chlorides.
- Reformatsky reactionOrganometallic addition The Reformatsky reaction (sometimes transliterated as Reformatskii reaction) is an organic reaction which condenses aldehydes or ketones with α-halo esters using metallic zinc to form β-hydroxy-esters.

- Reissert reaction The Reissert reaction is a series of chemical reactions that transforms quinoline to quinaldic acid.
- Retro-Diels–Alder reaction The retro-Diels–Alder reaction (rDA reaction) is the reverse of the Diels–Alder (DA) reaction, a [4+2] cycloelimination.
- Rieche formylation Rieche formylation is a type of formylation reaction.
- Riemschneider thiocarbamate synthesis The Riemschneider thiocarbamate synthesis converts alkyl or aryl thiocyanates to thiocarbamates under acidic conditions, followed by hydrolysis with ice water.
- Riley oxidationOxidation The Riley oxidation is a selenium dioxide-mediated oxidation of methylene groups adjacent to carbonyls.
- Ritter reaction The Ritter reaction (sometimes called the Ritter amidation) is a chemical reaction that transforms a nitrile into an N-alkyl amide using various electrophilic alkylating reagents.
- Robinson annulationCyclization The Robinson annulation is a chemical reaction used in organic chemistry for ring formation.
