Cannizzaro disproportionation: the reaction of aldehyde without α-H with alcohol and carboxylic acid in strong alkali (benzaldehyde).
Claessen-Claessen ester condensation: under the condition of strong base, one ester forms carbon anion, nucleophilic addition and elimination of another ester (one of the most important reactions in organic synthesis).
Clemenson reduction method: the reaction of reducing aldehydes and ketones to hydrocarbons (reducing carbonyl groups to methylene groups) under the action of zinc amalgam and concentrated hydrochloric acid.
Cope elimination reaction: the elimination reaction of tertiary amine treated with hydrogen peroxide and heat (Hoffman rule)
Corey-House Reaction: Coupling of Halogenated Hydrocarbons with Dialkyl Copper-lithium Reagents (An Important Reaction for Connecting Carbon Chains)
Cramer's law: nucleophiles attack preferentially from the side with low space resistance.
Dickerman-Dickerman condensation: The reaction is similar to ester condensation and cyclization.
Diels-Alder Diels-Adel reaction: generally, it is the reaction of 1, 3- butadiene derivative with ethylene derivative (synergistic reaction).
Feyning membrane reagent: the newly formed copper oxide oxidizes aldehyde into acid.
Friedel-Crafts reaction: The reaction of introducing hydrocarbon groups or acyl groups into benzene rings.
Gabriel synthesis method: primary amine was prepared by the reaction of phthalimide salt with halogenated hydrocarbon.
Geithmann-Koch Goldman-Robert Koch reaction: the reaction of aromatic hydrocarbons with hydrochloric acid and carbon monoxide to produce aromatic aldehydes.
Grignard reagent: one of the most important reagents in organic synthesis, which can prepare halogenated hydrocarbons, magnesium and ether.
Haworth Haworth Style: Stereoscopic Projection of Sugar
Hinsberg reaction: aromatic hydrocarbon is used to identify monoamines, diamines and triamines, and benzoyl chloride is used as the reagent.
Hoffman Hoffman elimination: the elimination reaction of quaternary ammonium alkali after heating, the reaction direction is opposite to Chaitoff's law.
Hoffmann degradation: amide generates amine with less than one carbon in bromine alkaline solution.
Huck's Huck's Law: When the number of π electrons is 4n+2, the closed loop is aromatic (except the tension of H in the ring).
Knoevernagel knoevengel reaction: condensation reaction of aldehydes and ketones with compounds containing α-H under weak base.
Lindar Lindera catalyst: Palladium was treated with calcium carbonate and lead acetate to reduce its activity and partially hydrogenate it.
Lucas reagent: a solution of anhydrous zinc chloride and concentrated hydrochloric acid, used to identify secondary or tertiary alcohols.
Mannich reaction: α-H ketone reacts with aqueous solution of formaldehyde and ammonium salt to produce β-aminoketone.
Markovnikov's Law: In the asymmetric olefin addition reaction, more carbon is hydrogenated by hydrogen.
Meerwein-Pendorf Meerwein-Pendorf Reduction Method: The reaction of reducing aldehydes and ketones to alcohols with aluminum isopropoxide.
