1-Bromonaphthalene Chemical Properties,Uses,Production

Chemical Properties

Thick colorless yellow to yellow-brown liquid with a pungent odor. Insoluble in water, miscible with alcohol, ether, benzene and chloroform. 1-Bromonaphthalene is one of two isomeric bromonaphthalenes, the other being 2-bromonaphthalene.

Uses

1-Bromonaphthalene is used in organic synthesis and refractometry of fats. It is used in the preparation of N-aryl imidazoles and diaryl ethers. It is used to determine the refractive index of crystals and the water content of alcohols. It is utilized in the preparation of glutathione peroxidase-like antioxidant activity of diaryl diselenides. Further, it serves as a solvent for the exfoliation and dispersion of hexabenzocoronene. In addition to this, it is used as a refrigerant and a solvent molecular weight substance.

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.

Preparation

1-Bromonaphthalene is synthesized by the reaction of naphthalene with bromine: C10H8+ Br2→ C10H7Br + HBr.
Reaction: add carbon tetrachloride and naphthalene in the reaction pot, stirring and heating, and slowly add bromine at 45℃. After adding, keep the reaction at 70-80℃ for 3-4h. distillation to recover carbon tetrachloride, wash the reaction product, distill under reduced pressure, wash again, filter, dry and get the finished product.
