General description
Sodium cyanoborohydride, also known as sodium cyanotrihydridoborate, is a mild reducing agent that is stable in acidic conditions. It is widely used in the selective reduction of aryl aldehydes and ketones.
Application
Sodium cyanoborohydride is used as a reagent:
- To convert the amino-functional Si3N4 surface to a reactive surface with aldehyde groups.
- For coupling amino-modified oligonucleotide probes.
- In the synthesis of a novel phenolate-bridged dilanthanum(III) complex of interest as a model for metalloproteins.
- In the reductive amination of aldehydes and ketones, and in the reductive alkylation of amines.
Reagent for selective reductions.
