Applicazioni

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.

Note

Incompatible with strong oxidizing agents and acids.

Letteratura

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):
