| | Tetrabutylammonium cyanoborohydride Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | Tetrabutylammonium Cyanoborohydride is used in preparation method of novel biomass plastic material. | | Uses | Reactant for:
- Hydroxymethylation reactions
- Radical carbonylation reactions
- Reduction reactions (reductant)
| | Application |
Tetrabutylammonium cyanoborohydride (TBAC) is used as a selective, mild reducing reagent for aldehydes, conjugated aldehydes and ketones, alkyl iodides and bromides; useful for reductive
aminations of aldehydes and ketones in nonpolar solvents.
| | Preparation | Tetrabutylammonium cyanoborohydride is prepared from n-Bu4NHSO4 suspended in H2O, treated with Sodium Hydroxide and Sodium Cyanoborohydride, and
extracted into CH2Cl2; recrystallized from ethyl acetate. Other tetraalkylammonium derivatives are available (including polymersupported) or can be generated in situ from NaBH3CN and Aliquat 336. | | reaction suitability | reagent type: reductant |
