Potassium Fluoride → HCID 59155917, compound

Participants

Reaction Steps

In THF, 0.155 g (0.201 mmols) of the 5,5″-diiodo-3′,4′-bis(diethoxyphosphoryl)-[2,2′;5′,2″]-terthiophene obtained in Example 7(4) and 0.307 g (0.422 mmols) of 5-tributylstannyl-3,4-bis(diethoxyphosphoryl)-[2,2′]-bithiophene obtained in Example 6(5) were dissolved, to which 0.0438 g (0.442 mmols) of commercially available copper(I) chloride was added at room temperature. Thereafter, the reaction mixture was heated and stirred under reflux for 18 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 silica gel column to obtain the specified substance in the form of a yellow oil at a yield of 0.216 g (yield: 77%).
