Description:
Sodium cyanoborohydride is the inorganic compound with the formula NaBH3(CN). This colourless salt is widely used in organic synthesis for the reduction of imines.
Sodium cyanoborohydride is a mild reducing agent that converts imines to amines. It can be used to exchange the oxygen for an amine group on the carbonyl carbon of aldehydes or ketones when reacted with ammonia or a primary amine. Selectivity is achieved at mildly basic solutions (pH 7-10). Owing to this selectivity, the reagent is ideal for reductive aminations. This reduction is known sometimes as the Borch Reaction. The salt is mildly water-sensitive, but tolerates aqueous conditions.In addition, sodium cyanoborohydride is often used in hydrogenolysis reactions, such as the opening of acetals.
