WitrynaThe equilibrium between aldehyde/ketone and imine can be shifted toward imine formation by removal of the formed water through physical or chemical means. This intermediate imine can then be isolated and reduced with a suitable reducing agent (e.g., sodium borohydride). This method is sometimes called indirect reductive … WitrynaSodium borohydride is considered to be a selective reagent, 31 which means that it is a weaker reducing agent when compared to LiAlH 4 (e.g., see Section 7.6).Sodium …
