Reaction Conditions

Reaction Steps

The dried THF (100 mL) is added with the 3-hexylthiophen (1 g, 5.94 mmol), cooled at −80° C., and slowly added with n-BuLi (5.94 mL, 14.85 mmol, 2.5 M in hexane) by one drop for 60 minutes. The reaction mixture is agitated at −80° C. for 3 hours. The reaction mixture is slowly added with tributyltin chloride (4.56 mL, 14.85 mmol) by one drop for 30 minutes. After the reaction mixture is agitated at −80° C. for 30 minutes, the reaction mixture rises to room temperature and is additionally agitated for 2 hours and is quenched with the NH4Cl aqueous solution. The reaction mixture is extracted with ethylacetate and then the organic layer is washed with water and dried with anhydrous sodium sulfate. The solvent was evaporated and the mixture before being purified was purified by the flash column chromatography using the silica gel quenched with triethylamine to obtain the desired compound 17 (4.21 g, 95% yield). 1H NMR (400 MHz, CDC13): δ=7.06 (s, 1H, CH—C-hexyl), 2.76-2.73 (t, J=12 Hz, 2H, ArCH2-, hexyl), 1.62 (m, 14H, ArCH2CH2-, hexyl+6×—(CH2)2-CH2-, butyl), 1.44-1.40 (m, 24H, 6×—(CH2)2-CH2-, butyl), 1.25-1.15 (m, 6H, CH3 (CH2)3-, hexyl), and 0.99-0.91 (m, 21H, CH3, hexyl+6×CH3, butyl) ppm. 13C NMR (100 MHz, CDC13): δ=144.30, 136.80, 136.05, 125.58, 31.64, 30.91, 29.25 29.09, 27.54, 27.37, 22.77, 14.12, 13.74, 10.78 ppm. C34H68SSn2 (746.39): calcd. C, 54.71; H, 9.18; S, 4.30; Sn, 31.81. found C, 54.59; H, 9.23; S, 4.40.
