Reaction Steps
4,4-bis(2-ethylhexyl)-2,6-bis(trimethylsilyl)-dithieno[3,2-b:2′,3′-d]silole (Compound G1, synthesized in accordance with Non-patent Document J. Am. Chem. Soc. 2008, 130, 16144-16145, 1.03 g, 1.786 mmol) was placed in a 200 mL four-necked recovery flask in a nitrogen atmosphere, and dissolved in chloroform (50 mL). Trifluoroacetic acid (0.265 mL, 3.573 mmol) was added dropwise, and the mixture was agitated for about 3.5 hours. Water was added to the reaction solution, and the lower layer was washed with water, dried over sodium sulfate, and concentrated under reduced pressure. This was dissolved in hexane and subjected to silica gel column chromatography (solvent: hexane) to obtain 4,4-bis(2-ethylhexyl)-dithieno[3,2-b:2′,3′-d]silole (Compound G2) as a light yellow oily substance (702 mg, yield 94%).
