Reactant for radical reductions of alkyl bromides with N-heterocyclic carbene boranes

Reactant for synthesis of tetramethylammonium trialkylphenylborate salts with oxidation potential
Triethylborane is used as a catalyst for:
  • Allylation of aldehydes
  • Decarboxylative C-C bond cleavage reactions
  • Rhenium hydride / boron Lewis acid cocatalysis of alkene hydrogenations
  • Regioselective hydroxyalkylation of unsaturated oxime ethers


It can be employed as a reactant for radical reductions of alkyl bromides with N-heterocyclic carbene boranes and for the synthesis of tetramethylammonium trialkylphenylborate salts.
