Acetone cyanohydrin, (CH 3) 2 C(OH)CN is the cyanohydrin of acetone. It is generated as an intermediate in the industrial production of methyl methacrylate . [ 3 ] In the laboratory, this liquid serves as a source of HCN, which is inconveniently volatile. [ 4 ]
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 ...
(CH 3) 3 SiCN + H 2 O → (CH 3) 3 SiOH + HCN. In its principal application, it adds across carbon-oxygen double bonds, for example in an aldehyde, to form a new carbon-carbon bond: [2] RCH=O + (CH 3) 3 SiC≡N → N≡C– CHR–O Si(CH 3) 3. The product is an O-silylated cyanohydrin. One use of this reagent is to convert pyridine-N-oxides ...
In transhydrocyanation, an equivalent of HCN is transferred from a cyanohydrin, e.g. acetone cyanohydrin, to another HCN acceptor. The transfer is an equilibrium process, initiated by base. The reaction can be driven by trapping reactions or by the use of a superior HCN acceptor, such as an aldehyde. [6]
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 used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium cyanide: [8] (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2. In transhydrocyanation, an equivalent of HCN is transferred from acetone cyanohydrin to another acceptor, with acetone as byproduct. The transfer is an equilibrium process, initiated by ...
