General description

1-Bromonaphthalene serves as an intermediate for the synthesis of biaryl compounds via cross-coupling reactions.

Application

1-Bromonaphthalene is a bromoarene that can be used in:
  • Palladium-catalyzed Suzuki–Miyaura coupling reaction with potassium aryltrifluoroborates without the use of phase-transfer catalysts or phosphine ligands.
  • The preparation of indeno annelated polycyclic aromatic hydrocarbons by reacting with o-bromobenzeneboronic acid and oligocyclic bromoarenes via Suzuki-Heck type coupling.
  • Ni catalyzed Kumada–Tamao–Corriu cross-coupling reaction with PhMgBr.
  • The preparation of arylnaphthalenes via palladium-catalyzed Suzuki-Miyaura cross-coupling reaction with aryl boronic acid.
