5-BROMO-2 2'-BITHIOPHENE 96 Chemical Properties,Usage,Production

Uses

5-Bromo-2,2′-bithiophene may be used in the synthesis of trimethyl-[2,2′;5′,2″;5″,2″]quaterthiophen-5-yl-silane (4TTMS) and 5-hexylsulfanyl-2,2′:5′,2′′-terthiophene.

General Description

5-Bromo-2,2′-bithiophene is a bromothiophene derivative. Its reaction with various aryl iodides bearing an electron-donating or electron-withdrawing substituent has been described. It can be synthesized from 2,2′-bithiophene.

Synthesis

492-97-7

3480-11-3

General procedure for the synthesis of 5-bromo-2,2-bithiophene from bithiophene: 3 g (18 mmol) of 2,2'-bithiophene and 50 mL of N,N-dimethylformamide (DMF) were placed in a 250 mL two-necked round-bottomed flask and dissolved by stirring. A solution of 3.2 g (18 mmol) of N-bromosuccinimide (NBS) dissolved in 10 mL of DMF was added slowly and dropwise under cooling in an ice bath. After completion of the reaction, the reaction mixture was extracted with dichloromethane (DCM) and the organic phase was collected. Purification by recrystallization from methanol (MeOH) gave 2.5 g of light yellow solid product in 56% yield. The resulting intermediate (1) was characterized by nuclear magnetic resonance hydrogen spectroscopy (1H NMR, CDCl3, 400 MHz) with the following chemical shifts: δ= 6.91 (1H, d), 6.96 (1H, d), 7.00 (1H, dd), 7.22 (1H).
