WebThe effect of electron-withdrawing substituents on the Birch Reduction varies. For example, the reaction of benzoic acid leads to 2,5-cyclohexadienecarboxylic acid, which can be … WebMay 3, 2014 · The reductive amination using sodium cyanoborohydride (NaBH3CN) as the reducing agent is especially called the Borch reaction and has high generality. NaBH 3 … The reagent is typically used in excess. Selectivity is achieved at mildly basic solutions (pH 7–10). [citation needed] The reagent is ideal for reductive aminations ("Borch Reaction"). In conjunction with tosylhydrazine, sodium cyanoborohydride is used in the reductive deoxygenation of ketones. See more 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 … See more 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 borohydride … See more 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 favored for reductive aminations, … See more • Sodium triacetoxyborohydride – a milder reductant, but unstable in water • Sodium borohydride – a stronger, cheaper reductant See more fangotherapy definition
