POTASSIUM TRIETHYLBOROHYDRIDE Usage And Synthesis

Chemical Properties

CLEAR SOLUTION

Uses

• Reducing agent for synthesis of PtNi intermetallic nanoparticle catalysts with electrocatalytic activity
• Reducing agent for preparation of vanadium nanoparticles (~7 nm) stabilized on activated carbon

• Preparation of lithium, sodium, and potassium boron monohydride complexes with tetramethylethylenediamine and pentamethyldiethylenetriamine
• Dehydrogenation reactions
• Tandem nucleophilic addition/C-C bond cleaving fragmentation reactions with cyclic vinylogous acyl triflates
• Preparation of coordinatively unsaturated pseudotetrahedral iron(II) precursors as precatalysts for the room-temperature hydrogenation of unsaturated hydrocarbons
• Substitution reactions

reaction suitability

reagent type: reductant

Synthesis

Potassium Triethylborohydride is prepared by the reaction of Potassium Hydride with Triethylborane in THF, or benzene. From Potassium Triisopropoxyborohydride and triethylborane in THF and from sodium triethylborohydride and potassium amalgam in benzene.

storage

The solution in THF is moisture- and air-sensitive, corrosive, and flammable. Reacts violently with water. Handle and store under nitrogen or argon in a cool place. Stable over prolonged periods of time. Use in a fume hood. Avoid contact with eyes, skin, and clothing.
