General description

Boron tribromide (BBr3) is a commonly used reagent in organic chemistry for demethylation.

Application

Reactant for preparation of:
  • Drug intermediate 6-nitro-L-DOPA
  • Luminescent polystyrene derivatives with sterically protected carbazolylborane moieties
  • High-quality boron-doped graphene via Wurtz-type reductive coupling reaction
  • Mercapto-(+)-methamphetamine haptens for synthesis of (+)-methamphetamine conjugate vaccines with improved epitope densities
  • Micrometer-sized organic molecule-DNA hybrid structures
  • Borane complexes via electrophilic aromatic borylation reactions
  • A 5-HT2C receptor agonist
  • Biphenyl-derivatives possessing tertiary amino groups as ß-secretase(BACE1) inhibitors for the treatment of Alzheimer′s disease
  • A highly near-IR region fluorescent p-extended boron aza-dipyrromethene moiety unit
  • Tetrahydroisoquinoline derivatives via intramolecular cyclization of methoxy-substituted N-phenethylimides
Used to cleave aryl methyl ethers in a synthesis of a benzopyranobenzopyran from a coumarin scaffold.
