Application

Borane triethylamine complex is a general reagent which can be used in the synthesis of silylhydroboranes and meso-triarylsubporphyrins. It can also be used in the preparation of liquid-phase hydrogen storage material.
Used for:
  • Ethanolysis of amine-borane adducts producing a reducing system
  • Photochemical hydroboration and oxidation of single-walled carbon nanotubes

Reactant for the synthesis of:
  • Silylboranate
  • N-heterocyclic carbene borane complexes via Lewis base exchange with amine-boranes
  • Boron carbide nitride films via low-pressure CVD
  • (Pyridine)tripyrrolylboron

Reactant for modification of the radionuclide 211 At for astatination of biomolecules
