Salts containing new cyanido(fluorido)phosphate anions of the general formula PF6-n(CN)n (n=1-4) were synthesized by a very mild Lewis-acid-catalyzed synthetic protocol and fully characterized. All PF6-n(CN)n (n=1-4) salts could be isolated on a preparative scale. It was also possible to detect the PF(CN)5 but not the P(CN)6 anion. The best results with respect to purity, yield, and low cost were obtained when the F(-)/CN(-) substitution reactions were carried out in ionic liquids.
通过一种非常温和的路易斯酸催化合成方法合成了通式为PF6-n(CN)n（n = 1 - 4）的含新型氰基（氟基）磷酸根阴离子的盐，并对其进行了全面表征。所有PF6-n(CN)n（n = 1 - 4）盐都可以在制备规模上分离得到。还能够检测到PF(CN)5阴离子，但未检测到P(CN)6阴离子。当在离子液体中进行F(-)/CN(-)取代反应时，在纯度、产率和低成本方面获得了最佳结果。
