Versuchsvorschrift

2-bromo-3-decanyldithieno[3,2-b:2′,3′-d]thiophene (92)(4.16 g, 0.01 mol) was mixed with 1-decyne (3.6 g, 0.026 mol), tetrakis(triphenylphosphine)palladium (0.58 g, 0.5 mmol) and copper(I) iodide (0.19 g, 1.0 mol) in triethylamine (80 mL). This mixture was bubbled with nitrogen for 5 minutes and then heated up to 130° C. under argon for 16 hours. Triethylamine was evaporated and hexane (150 mL) was added. This mixture was filtered to remove solid salts. The organic layer was washed with 1 M hydrochloric acid (50 mL) and brine (50 mL) then dried over MgSO4. The solvent was removed in vacuo, and the residue was purified by chromatography on silica gel eluting with hexane to yield the target compound (3.87 g, 93.0%). 1HNMR, solvent CD2Cl2. δ 7.36 (d, 1H), 7.30 (d, 1H), 2.82 (t, 2H), 2.49 (t, 2H), 1.63-1.27 (m, 28H), 0.88 (m, 6H).
