Abstract:
1. A method for preparing salts of weakly coordinating anions of the type corresponding to the following formula (1), (2) or (3): wherein, in a first step an organyl compound of an element XR m is reacted with a partially or completely fluorinated alcohol F ROH in an organic, aprotic solvent and then, in a second step, the resulting alkoxy compound of the element X(OR F ) m is reacted with a suitable fluoride salt M y Y z so as to abstract a fluoride ion, if necessary under XF m -catalysis, wherein X is selected from the group consisting of B, Al, Ga, In, P, As and Sb, M is a monovalent or bivalent cation, m is 3 or 5 and n is 2, if m is 3, and/or n is 4, if m is 5, y is 1 or 2, provided that, if y is 1, Y is a monovalent anion, or if y is 2, Y is a bivalent anion, and z is 1 or 2, provided that, if z is 1, M is a monovalent cation, or if z is 2, M is a bivalent cation.
