Sodium cyanide is used as a starting material for the preparation of Reissert compounds and cyanogen bromide, cyanuric chloride and cyanogen chloride. It acts as a catalyst for the aminolysis of esters to primary amides. Furthermore, it is used for fumigation, electroplating, extracting gold and silver in mining industry. In organic synthesis, it is involved in the cyanation reaction of alkyl halides under phase transfer conditions.
Cyanations of alkyl halides are often carried out most conveniently under phase-transfer conditions: Synth. Commun., 6, 193 (1976); see: E. V. Dehmlow and S. S. Dehmlow, Phase-Transfer Catalysis, 3rd ed., VCH, N.Y. (1993), for further extensive examples. DMSO is also a good solvent for these reactions: J. Org. Chem., 25, 257, 877 (1960).
