Potassium Fluoride → HCID 59155962, compound

Participants

Reaction Steps

At room temperature, 0.1235 g (0.33 mmols) of 2-iodoterthiophene and 0.0069 g (0.006 mmols) of commercially available tetrakistriphenylphosphine palladium were dissolved in 2 ml of toluene, to which 0.1693 g (0.15 mmols) of 4,4′-bis(dibutoxyphosphoryl)-5,5′-bis(tributylstannyl)-[2,2′]-bithiophene was 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 saturate 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=1:10) to obtain the specified substance in the form of a red solid at a yield of 0.1143 g (yield: 73%).
