主权项

1. A process for the preparation of a compound of formula (1)
[Kt]x+[(CnF2n+1)ZPF5-zH]−x,  (1)in which [Kt]x+ is an inorganic or organic cation, n is 1-8, x is 1-4, and z is 1-4, said process comprising:
in a first step, reacting a compound of formula (2)
(CnF2n+1)zPF5-z  (2) with a hydride ion donor, and
if [Kt]x+ in formula (1) is an organic cation, in a second step, optionally reacting the product from said first step with a compound of formula (3)
[Kt]x+[X]−x,  (3),in which [Kt]x+ stands for an organic cation and [X]− stands for a hydrophilic anion.
