2-Bromonaphthalene is used as a raw material in the preparation of biaryls through Suzuki cross coupling reaction. Further, it plays a vital role in the preparation of dyes. It is also used to study potential tumorigenicity.
Reaction of 2-bromonaphthalene with cuprous cyanide in N-methylpyrrolidone has been investigated. Nanosecond time-resolved resonance Raman spectra of the T1→Tn transition of 2-bromonaphthalene in methanol solvent has been investigated.
Purify 2-bromonaphthalene by fractional elution from a chromatographic column of activated alumina. Crystallise it from EtOH. [Beilstein 5 IV 1667.]
