Yield	Reaction Conditions	Operation in experiment
47%	With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,2-dimethoxyethane; water; at 90℃; for 16h;Inert atmosphere;	To a 100 ml two-necked round bottom flask was added 1,2-bis (5-bromo-2-methylthiophen-3-yl) perfluorocyclopentene (1.58 g, 3 mmol)4'-octyloxybenzeneboronic acid (0.75 g, 3 mmol),Anhydrous sodium carbonate (1.59 g, 15 mmol)Water (6 ml) and ethylene glycol dimethyl ether (DME, 24 ml) and stirred with magnetic force,Nitrogen was bubbled through the mixture for 30 min to completely remove the solvent and the oxygen in the reaction system.Then, palladium palladium catalyst Pd (PPh3) 4 (0.17 g, 0.15 mmo 1) was added under a nitrogen stream,Immediately with a double row of tubes carefully evacuated nitrogen three times, so that the entire system strictly oxygen.The temperature was raised to 90 C and the reaction was stirred for 16 h.After the temperature was returned to room temperature, the product was extracted with ether,Washed three times, dried by anhydrous sodium sulfate and filtered,The solvent was purified by silica gel column chromatography (eluting with a mixture of n-hexane / dichloromethane = 1: 19) to give 0.92 g of a purple solid in 47% yield,
	With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,2-dimethoxyethane; water; at 90℃; for 20h;Inert atmosphere;	Ethylene glycol dimethyl ether was purged with nitrogen for 30 minutes to remove dissolved oxygen, and the raw material was n-decylphenylboronic acid (0.90 g, 3.6 mmol).1,2-bis(5-bromo-2-methylthien-3-yl)perfluorocyclopentene (DTE-2Br) (1.58 g, 3 mmol) and sodium carbonate (1.59 g, 15 mmol) according to charge ratio 1:1.2 : 5 uniformly dispersed in a 4:1 mixture of ethylene glycol dimethyl ether and water,The catalyst tetrakis(triphenylphosphine)palladium (0.17 g, 0.15 mmol) was added under nitrogen atmosphere and extracted three to four times.The reaction temperature was 90C and the reaction time was 20 hours.After completion of the reaction, the organic layer was collected and purified by column chromatography to give the product C8H17O-DTE-Br.
