PyridineN‐oxide–BF2CF3 and –BF2C2F5 complexes and their derivatives were synthesized. Most of the complexes show fluorescence both in solution and in the solid state. By expanding the π‐conjugated skeleton, the color of the fluorescence could be changed dramatically. A fluorophore with a high solvent dependency could also be produced. Since such compounds can be synthesized on a gram scale in high
ionic liquids and organic salts with [RFBF3]− anions, in general, and for the synthesis of further perfluoroalkylborate anions, for example perfluoroalkylcyanofluoroborates [RFBF3-n(CN)n]− (n = 1–3). Furthermore, complex metal cations are accessible with the weakly coordinating [RFBF3]− counterions, as exemplified by the synthesis of [Cu(bpy)3][C2F5BF3] (bpy = 2,2′-bipyridine).
在酸性介质中,即在盐酸(37%),冰醋酸和三氟乙酸中以及在酸性离子液体中,通过氟化氢钾的作用,全氟烷基三甲氧基硼酸酯可以高产率转化为相应的全氟烷基三氟硼酸酯。这些低成本的方法避免了使用有毒和腐蚀性的氢氟酸或无水HF(aHF)。通常,全氟烷基三氟硼酸钾和钠是非常有价值的原料,通常用于制备低粘度的离子液体和含有[R F BF 3 ] -阴离子的有机盐,以及用于合成其他全氟烷基硼酸根阴离子,例如全氟烷基氰基氟硼酸盐[R F BF 3 -n(CN)n] -(n = 1-3)。此外,可以通过弱配位的[RF F BF 3 ] -抗衡离子获得复杂的金属阳离子,例如合成[Cu(bpy)3 ] [C 2 F 5 BF 3 ](bpy = 2,2'-bipyridine )。
