Participants

Reaction Steps

At room temperature, 0.0925 g (0.082 mmols) of 3″,4″′-bis(dibutoxyphosphoryl)-5,5″″′-diiodo-[2,2′;5′,2″; 5″,2″′;5″′,2″″;5″″,2″″′]-sexithiophene and 0.0076 g (0.0065 mmols) of commercially available tetrakistriphenylphosphine palladium were dissolved in 3 mL of toluene, to which 0.1508 g (0.16 mmols) of 3′,4″-bis(dibutoxyphosphoryl)-5″-(tributylstannyl)-[2,2′;5′,2″]-terthiophene and 0.0029 g (0.032 mmols) of commercially available copper(I) chloride were added at room temperature. Thereafter, the reaction mixture was heated and stirred under reflux for 2 hours. After the reaction, the reaction mixture was cooled down to room temperature, to which a potassium fluoride aqueous solution was added, followed by stirring for 1 hour. Subsequently, the solid was removed by celite filtration and the filtrate was extracted 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 crude product was purified with a PTLC plate (developed with ethyl acetate:hexane=2:1 and ethyl acetate:hexane=3:1) to obtain the specified substance in the form of a red solid at a yield of 0.0720 g (yield: 41%).
