Nacnbh3 reductive amination
Witryna3 maj 2014 · The reductive amination using sodium cyanoborohydride (NaBH3CN) … 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 The tetrahedral BH3(CN) comprises the anionic component of the salt. The reagent is often purchased, although it can be … Zobacz więcej • Sodium triacetoxyborohydride – a milder reductant, but unstable in water • Sodium borohydride – a stronger, cheaper reductant Zobacz więcej
