investigated on several new kinds of perfluoroalkyl-substituted tetraarylborate ions such as tetrakis(3,5-bis(nonafluorobutyl)phenyl)borate, tetrakis(3,5-bis(heptafluoro-2-propyl)phenyl)borate (PFPB), tetrakis(3-(heptafluoro-2-propyl)-1-(trifluoromethyl)phenyl)borate, and tetrakis(3-(heptafluoro-2-propyl)phenyl)borate. Solubilities of tetramethylammonium tetraarylborates in some hydrophobic halocarbon
研究了几种新型的全氟烷基取代的四芳基硼酸根离子,如四(3,5-双(九氟丁基)苯基)硼酸根,四(3,5-双(七氟-2-丙基)苯基)硼酸根(PFPB)),四(3-(七氟-2-丙基)-1-(三氟甲基)苯基)硼酸酯和四(3-(七氟-2-丙基)苯基)硼酸酯。测定了四芳基硼酸四甲基铵在某些疏水性卤代烃溶剂中的溶解度,以及在甲醇硫酸溶液和二氯甲烷/硫酸水两相体系中酸催化的四芳基硼酸根离子分解的速率常数。与先前描述的范围比较,讨论了三氟甲基和全氟烷基取代基对四芳基硼酸根离子的亲脂性和化学稳定性的影响。
