Embodiment 1
[0085] (1) p -Nafluorobutylaniline
[0086] Add 3.44 g of p-bromoaniline, 5 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide (DMSO) into a 250 ml three-neck flask equipped with a magnetic stirrer, a thermometer and a condenser tube, stir and heat to 60 °C. Then 9 g of nonafluoroiodobutane was dissolved in 25 ml of DMSO and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the nonafluoroiodobutane solution was added dropwise, the reaction system was heated to 120 °C and refluxed for 24 h. The reaction system was cooled to room temperature, and the reaction was poured into a 500 ml beaker, 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash it with deionized water (30 ml x 3 times), dry over anhydrous magnesium sulfate for 8 h, filt...
Embodiment 2
[0101] (1) p -Synthesis of Tridecafluorohexylaniline
[0102] Add 3.44 g of p-bromoaniline, 5 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide (DMSO) into a 250 ml three-neck flask equipped with a magnetic stirrer, a thermometer and a condenser tube, stir and heat to 60 °C. Then 11.6 g trifluoroiodohexane was dissolved in 25 ml of DMSO and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the dropwise addition of tridecafluoroiodohexyl solution was completed, the reaction system was heated to 120 °C and refluxed for 24 h. The reaction system was cooled to room temperature, the reaction was poured into a 500 ml beaker, 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash it with deionized water (30 ml x 3 times), dry over anhydrous ...
Embodiment 3
[0114] (1) p -Heptadecafluorooctylaniline
[0115] Add 3.45 g of p-bromoaniline, 5.15 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide into a 250 ml three-neck flask equipped with a magnetic stirring bar, a thermometer and a condenser, and heat to 60 °C with stirring. Then 9.21 g of heptadecafluoroiodoctane was dissolved in 25 ml of dimethyl sulfoxide and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the nonafluoroiodobutane solution was added dropwise, the temperature of the reaction system was raised to 115° C. and refluxed for 12 hours. The reaction system was cooled to room temperature, and the reaction was poured into a 500 ml beaker, 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash with deionized water (30 ml × 3 time...
