Sodium cyanoborohydride is the chemical compound with the formula NaBH3CN. It is a colourless salt, but commercial samples can appear tan. It is widely used in organic synthesis for the reduction of imines. The salt tolerates aqueous conditions. Zobacz więcej Owing to the presence of the electron-withdrawing cyanide substituent, [B(CN)H3] is less reducing than is [BH4] . As a mild reducing agent, it is used to convert imines to amines. It is especially … Zobacz więcej • Sodium triacetoxyborohydride – a milder reductant, but unstable in water • Sodium borohydride – a stronger, cheaper reductant Zobacz więcej The tetrahedral BH3(CN) comprises the anionic component of the salt. The reagent is often purchased, although it can be prepared easily. One method involves combining sodium cyanide and borane. Another route entails treating sodium … Zobacz więcej Witryna5 sty 2024 · 5.7.19 Reduction of oximes and imine derivatives. ... (NaBH3CN), can also be used.
