Chloroacetonitrile is used in the electrochemical synthesis of cyanoacetic acid with carbon dioxide. It is involved in phase-transfer-catalyzed Darzen's condensation reaction with cyclohexanone. It is also used as an eluent additive in thermospray liquid chromatography/mass spectrometry. Further, it is used to prepare polysubstituted pyrido[1,2-a]benzimidazole by reacting with other reactant such as malononitrile, aromatic aldehyde and pyridine.
Forms cyanomethyl esters with carboxylic acids, e.g. in the presence of Et3N, which are a useful protection method; the esters are readily cleaved by Na2S in aqueous acetone: Synth. Commun., 22, 693 (1992).
Good yields of ß-hydroxy nitriles have been obtained by Reformatsky-type reaction with aldehydes and ketones using Zn and TMS chloride: Tetrahedron Lett., 31, 2205 (1990). See Bromoacetonitrile, A13933.
In the presence of base, Darzens condensation with aldehydes and ketones, under conventional or phase-transfer conditions, gives glycidonitriles (cyano epoxides), readily converted to the homologated carboxylic acids, esters or aldehydes with loss of cyanide: J. Chem. Soc., Chem. Commun., 988 (1974); Coll. Czech. Chem. Commun., 53, 822 (1988).
Ritter reaction with tertiary alcohols yields 2-chloroacetamides which, on treatment with thiourea, provides a high-yield conversion of tertiary alcohols to the corresponding amines: Synthesis, 1709 (2000):
