2,6-DIBROMO-1,5-DIHYDROXYNAPHTHALENE Chemical Properties,Usage,Production

Uses

2,6-Dibromo-1,5-naphthalenediol is a useful synthetic intermediate. It is used to prepare semiconducting polyphenyls and polythiophenes via microwave-assisted Suzuki and Stille cross-coupling reactions. It is also used to prepare and polymerize adamantane or phenylenevinylene or naphthalenevinylene-containing monomers.
