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
