2,5-Dibromo-3-octylthiophene Usage And Synthesis

Chemical Properties

Colorless to yellow to brown liquid

Uses

It is a conducting polymer precursor.

Synthesis

To a solution of 3-octylthiophene (65 g, 333 mmol) in DMF (200 mL) at 0??C was slowly added N-bromosuccinimide (130 ) through a dropping funnel. g, 733 mmol) in DMF (200 mL) . The mixture was stirred in the dark for 72 hours. The reaction mixture was poured over NaOH solution (300 mL, 2.5 M) and stirred at 0??C. The mixture was extracted with ether and the combined organic layers were washed with NaOH (2.5 M) and brine. . The organic layer was dried with MgSO 4 and the solvent was evaporated to give the yellow oily product 2,5-dibromo-3-octylthiophene (86% yield, 101 g).
