Participants

Reaction Steps

2.5 M of n-BuLi (2.04 mL/hexane, 5.09 mmol) was added to dithieno[3,2-b;2′,3′-d]thiophene 20 (1 g, 5.09 mmol/THF (20 mL)) and reacted at 0° C. for 1 hour under a dry and anaerobic operation condition to form a solution. SnBu3Cl (1.58 mL, 5.6 mmol) was then added to the solution and reacted at 0° C. for 30 minutes. After returning to room temperature, the solution was continuously reacted for 8 hours. After the reaction was completed, the solution was extracted by ether (30 mL) and deionized water (50 mL). An organic phase was collected. After removal of ether by a rotary concentrator, the organic phase was purified by reduced-pressure distillation to form a transparent pale yellow oily product (25, 2.1 g, 85%).
