The Bucherer reaction in organic chemistry is the reversible conversion of a naphthol to a naphthylamine in the presence of ammonia and sodium bisulfite. The reaction is widely used in the synthesis of dye precursors aminonaphthalenesulfonic acids.

Nucleophilic addition of aminonitrile to CO2 leads to cyano-carbamic acid, which undergoes an intramolecular ring closing to 5-imino-oxazolidin-2-one. The 5-imino-oxazolidin-2-one rearranges to form the hydantoin product via an isocyanate intermediate. my babys faceWebBucherer reaction; Bucherer-Bergs reaction; Büchner ring expansion; Buchwald-Hartwig amination; Burgess reagent; Burke boronates; Cadiot-Chodkiewicz coupling; Cadogan-Sundberg indole synthesis; Camps quinoline synthesis; Cannizzaro reaction; Carroll rearrangement; Castro-Stephens coupling; C-H activation.
