| | 2,3-Dibromobenzo[b]thiophene Usage And Synthesis |
| 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 | 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). | | References | [1] Patent: JP2017/160159, 2017, A. Location in patent: Paragraph 0049
