実験手順: A solution of thiophene (46.4 g, 551 mmol., 2.50 equiv.) and THF (300 mL) was cooled to −78° C. n-Butyllithium (2.5 M in hexanes, 212 mL, 528 mmol., 2.40 equiv.) was added over 1 hour. The mixture was stirred for an additional 30 minutes at −78° C. before a solution of 1-iodo-2-hexyldecane (90.0 g, 220 mmol., 1.00 equiv) in THF (200 mL) was added slowly over 1 hour. After stirring for 1 hour at −78° C., the reaction mixture was warmed to ambient temperature and stirred for 18 hours. Water (200 mL) was added and the organic material was extracted with Et2O (3×250 mL), washed with additional water, dried over Na2SO4, filtered, and concentrated in vacuo. The resulting brown residue was purified by silica gel column chromatography (hexanes) to give a pale yellow oil (52.03 g, 77% yield). 1H NMR (500 MHz, CDCl3) δ 7.12 (dd, J=5.2, 1.2 Hz, 1H), 6.92 (m, 1H), 6.76 (dd, J=3.4, 0.9 Hz, 1H), 2.76 (d, J=6.7, 2H), 1.62 (b, 1H), 1.33-1.21 (m, 24H), 0.91-0.87 (m, 6H). was added over 1 hour was added slowly over 1 hour the reaction mixture was warmed to ambient temperature stirred for 18 hours the organic material was extracted with Et2O (3×250 mL) washed with additional water dried over Na2SO4 filtered concentrated in vacuo The resulting brown residue was purified by silica gel column chromatography (hexanes)
