1160823-77-7

General procedure for the synthesis of 4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-B:4,5-B']dithiophene from 2-ethylhexyl bromide and benzo[1,2-B:4,5-B']dithiophene-4,8-dione: Weighing 2.2 g of benzo[1,2-b:4,5-b']dithiophene-4,8-dione, adding 1.5 g zinc powder, 6 g sodium hydroxide , 35 g distilled water, heated to reflux, the oil bath temperature was controlled at 120 °C, and the reaction time was 13 h; the solution rapidly changed from yellow to red. As the reaction proceeded, the solution became homogeneous. At this time, 5.8 g of 2-ethylhexyl bromide and 0.11 g of tetrabutylammonium bromide (TBAB) were added as catalysts. As the reaction proceeded, the solution changed from black to red and eventually to light yellow. Termination of the reaction: quenching with water. Post-reaction treatment: extraction with ether several times, drying with anhydrous magnesium sulfate, rotary evaporation to remove the solvent, drying in vacuum to constant weight, the product 4,8-bis(2-ethylhexyloxy)benzo[1,2-b:4,5-b']dithiophene was obtained as 3.9 g in 87% yield.
