General description

Acetone cyanohydrin serves as a source of hydrogen cyanide in the Mitsunobu reaction. Also an intermediate for methacrylamide synthesis.

Application

Acetone cyanohydrin can be used as a cyanide source for:
  • Cyanation reactions of aryl halides, aldehydes and alcohols.
  • Stereospecific epoxide ring opening.
  • Strecker reaction of α-amido sulfones to synthesize α-amino nitriles.
