Versuchsvorschrift

In DMF, 0.0971 g (0.159 mmols) of 2,5-diiodo-3,4-bis(diethoxyphosphoryl)thiophene and 0.0346 g (0.349 mmols) of commercially available copper(I) chloride were dissolved, to which 0.1744 g (0.383 mmols) of tributylstannylbithiophene was added at room temperature. Thereafter, the reaction mixture was heated to 80° C. and stirred for 12 hours. After the reaction, the reaction mixture was cooled down to room temperature, to which a 0.6 M hydrochloric acid aqueous solution was added, followed by extraction of the resulting product with ethyl acetate. The organic phase was washed with a saturated saline solution and dried over anhydrous sodium sulfate. The solvent was removed by distilling off under reduced pressure, and the resulting product was purified with a silica gel column (ethyl acetate:methanol=15:1) to obtain the specified substance 1. The results are shown in Table 12.
