Description and Uses
Sodium triacetoxyborohydride, also known as sodium triacetoxyhydroborate, commonly abbreviated STAB, is a white hygroscopic solid that emits hydrogen gas when hydrolysed in water, which is flammable. STAB is a milder reducing agent than sodium borohydride or even sodium cyanoborohydride. Even sodium cyanoborohydride is a milder reducing agent than sodium borohydride, and is particularly suitable for the reductive amination of aldehydes and ketones. It can reduce aldehydes but not most ketones. It can also be used in the reductive alkylation of secondary amines in aldehyde-bisulfite adducts.
Sodium Triacetoxyborohydride(STAB) is a hydride reagent used in stereoselective reductive amination. It is able to replace toxic sodium cyanoborohydride under most conditions. It is selective in reducing aldehydes to alcohols in the presence of ketones. STAB is also stable in anhydrous acids, which enables reductive amination of aldehydes and ketones. It used in reductive amination of ketones and aldehydes and reductive amination/lactamization of carbonyl compounds with amines. The advantage of STAB compared to sodium cyanoborohydride is evident. STAB, being non-toxic, is easier to handle and forms no toxic by-products, making the treatment of process waste after the reaction simple and less costly.
