  2. Cyanohydrin reaction - Wikipedia

    en.wikipedia.org/wiki/Cyanohydrin_reaction

    In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion ...

  3. Cyanohydrin - Wikipedia

    en.wikipedia.org/wiki/Cyanohydrin

    The structure of a general cyanohydrin. In organic chemistry, a cyanohydrin or hydroxynitrile is a functional group found in organic compounds in which a cyano and a hydroxy group are attached to the same carbon atom. The general formula is R 2 C(OH)CN, where R is H, alkyl, or aryl.

  4. On-water reaction - Wikipedia

    en.wikipedia.org/wiki/On-water_reaction

    The reaction of quadricyclane with DEAD is a 2σ + 2σ + 2π cycloaddition that on water takes place within 10 minutes at room temperature with 82% yield. The same reaction in toluene takes 24 hours at 80 °C with 70% yield. An emulsion reaction in fluorinated cyclohexane takes 36 hours and the neat reaction takes even longer (48 hours).

  5. Kiliani–Fischer synthesis - Wikipedia

    en.wikipedia.org/wiki/Kiliani–Fischer_synthesis

    The Kiliani–Fischer synthesis, named for German chemists Heinrich Kiliani and Emil Fischer, is a method for synthesizing monosaccharides.It proceeds via synthesis and hydrolysis of a cyanohydrin, followed by reduction of the intermediate acid to the aldehyde, thus elongating the carbon chain of an aldose by one carbon atom while preserving stereochemistry on all the previously present chiral ...

  7. Cyanation - Wikipedia

    en.wikipedia.org/wiki/Cyanation

    Cyanation of ketones or aldehydes yields the corresponding cyanohydrins, which can be done directly with the cyanide ion (the cyanohydrin reaction) or by using bisulfite, followed by displacement of sulfite: [3] [4] Cyanation of aldehyde with bisulfite. A related reaction is hydrocyanation, which installs the elements of H-CN.

  8. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    Cyanide is unstable in water, but the reaction is slow until about 170 °C. It undergoes hydrolysis to give ammonia and formate, which are far less toxic than cyanide: [14] CN − + 2 H 2 O → HCO − 2 + NH 3. Cyanide hydrolase is an enzyme that catalyzes this reaction.

  9. Fischer oxazole synthesis - Wikipedia

    en.wikipedia.org/wiki/Fischer_oxazole_synthesis

    The product, which is the 2,5-disubstituted oxazole, precipitates as the hydrochloride and can be converted to the free base by the addition of water or by boiling with alcohol. [ 1 ] The cyanohydrins and aldehydes used for the synthesis are usually aromatic , however there have been instances where aliphatic compounds have been used.
