1,8-Dibromonaphthalene Chemical Properties,Uses,Production
Chemical Properties
White to yellow powder/crystals.
Application
1,8-Diarylnaphthalene show great potential in highly efficient photoluminescent blue and green OLEDs, chiral ligands and sensors, nonlinear optic chromophores, stereo-dynamic switches and other optoelectronic devices.
Preparation
1,8-dibromonaphthalene was prepared by diazotisation of triazine 1 with sodium nitrite in sulfuric acid, followed by the addition of CuBr/HBr in 44% yield, and cyanation of the dibromide (5) by Weissman’s method gave naphthalene-1,8-dicarbonitrile (4) in 78% yield (Scheme 2).
Reactions
Influence of the conditions on the Pd-catalyzed reaction of 1,8-dibromonaphthalene with 1,2,3,4-tetrafluorobenzene.
Scope of the Pd-catalyzed direct arylation reaction of 2,5-substituted heteroarenes with 1,8-dibromonaphthalene.
Structure and conformation
1,8-Dibromonaphthalene (1,8-DBN) is a symmetrical double bromo-substituted naphthalene with two bromos sitting at the naphthalene ring mirroring each other along the joining carbons.
