Yield:96216-36-3 85 %
Reaction Conditions:
with bromine in chloroform at 0;
Steps:
2.6. 2,5-Bis(4-bromophenyl)-3,4-diphenylyhiophene (TPTh-Br2)
A solution of TPTh (5.00 g, 12.8 mmol) and Br2 (4.20 g) in CHCl3 (40 mL) was cooled at 0 °C (ice bath) for 4 h. After evaporation of the solvent, the residue was washed with EtOH to give a yellow solid (85%) (Scheme S4). FTIR (KBr, cm-1, Figure S8): 3047.38 (C-Haromatic). 1H NMR (500 MHz, DMSO-d6,δ , ppm, Figure S9): 7.37-6.81 (ArH). 13C NMR(125 MHz, DMSO-d6, δ, ppm, Figure S10): 140.87-121.97 (Th and aromatic carbon nuclei).
