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 ...
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.

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.
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 ...
Glycolonitrile, also called hydroxyacetonitrile or formaldehyde cyanohydrin, is the organic compound with the formula HOCH 2 CN. It is the simplest cyanohydrin and it is derived from formaldehyde. [3] It is a colourless liquid that dissolves in water and ether.
What happened in the "Yellowstone" Season 5 finale? Fans react to Beth killing her brother Jamie and question whether Beth and Rip will get a spinoff.
The cyanohydrin itself is derived from a separate aldehyde. The reactants of the oxazole synthesis itself, the cyanohydrin of an aldehyde and the other aldehyde itself, are usually present in equimolar amounts. [3] Both reactants usually have an aromatic group, which appear at specific positions on the resulting heterocycle. Fischer Oxazole ...
