反応手順

2-Hexylthiophene (23.0 g, 0.137 mol) was dissolved in 250 ml THF and n-BuLi (94 ml, 1.6 M in hexanes, 0.150 mol) was added dropwise at 0° C. The mixture was stirred at 0° C. for 1 h and then cooled down to −78° C. A solution of trimethyltin chloride (32.8 g, 0.164 mol) in 100 ml THF was added dropwise. The mixture was allowed to warm slowly to room temperature and stirred for 2 h. After quenching with ice water and aqueous work-up, the product was distilled at 108° C. under high vacuum. 5-Hexyl-2-trimethylstannylthiophene was obtained as a colourless liquid (40.8 g, 90% yield).
