Tetrahydrofuran → (2-Allyloxy-3-tert-butyl-5-methylphenyl)(cyclopenta[1,2-b:4,3-b']dithiophen-7-yl)diethylsilane

To a solution of cyclopenta[1,2-b:4,3-b′]dithiophene (0.50 g, 280 mmol) in tetrahydrofuran (25 mL) was added dropwise n-butyllithium (1.56 M, 1.88 mL, 2.94 mmol) at −78° C. and stirred at room temperature for 4 hours. The mixture was cooled to −78° C. and a solution of (2-allyloxy-3-tert-buyl-5-methylphenyl)chlorodimethylsilane (0.83 g, 2.80 mmol) in toluene (5 mL) was added dropwise thereto. The resulting reaction mixture was warmed to room temperature and stirred for 2 hours. After the solvent was distilled off under reduced pressure, toluene was added and the mixture was filtered to remove insoluble substances. The filtrate was concentrated under reduced pressure to quantitatively obtain (2-allyloxy-3-tert-butyl-5-methylphenyl)(cyclopenta[1,2-b:4,3-b′]dithiophen-7-yl)diethylsilane.
