2,3-Dibromobenzo[b]thiophene Chemical Properties,Usage,Production

Uses

2,3-Dibromothioindene is an organic intermediate that can be obtained by brominating benzothiophene and is used to prepare luminescent materials.

Chemical Properties

White to yellow solid

Synthesis

95-15-8

6287-82-7

Using benzothiophene as starting material in dichloromethane (DCM) solvent, potassium acetate was added as a base, followed by bromination reaction with dropwise addition of bromine to give 2,3-dibromothiophene (compound 12) as a white solid in 100% yield. In addition, the target compound X can be synthesized by replacing compound (11) in formula (1).
