摘　　要：用三氟化硼与二苯亚砜反应,合成四氟硼酸二氟氧硼二苯基锍。采用红外光谱、紫外光谱、19 F NMR对产物的结构进行表征,测试了其电导率和热稳定性。结果表明,四氟硼酸二氟氧硼二苯基锍为离子型化合物,在-70℃至45℃为稳定液体,使用四氟硼酸二氟氧硼二苯基锍引发了四氢呋喃和环氧丙烷的开环共聚反应。Tetrafluoroborate difluoro-borodiphenyl sulfide is synthesized through reaction of boron trifluoride and diphenyl sulfoxide.The structure of the product is represented by infrared spectrum,ultraviolet spectrum and 19 F NMR,and its electrical conductivity and thermal stability are tested.The results show that tetrafluoroborate difluoro-borodiphenyl sulfide is an ionic compound and is a stable liquid at the temperature range from-70℃to 45℃.The use of tetrafluoroborate difluoro-borodiphenyl sulfide leads to open-ring copolymerization reaction of tetrahydrofuran and epoxypropane.
