Abstract
The invention relates to a method for the production of salts of weakly coordinating anions of the type according to the following formula (1), (2) or (3): M[F—X(OR F)m]z (1), M[(FRO)mX—F—X(ORF)m]z (2), M[(FRO)mX—F—X(ORF)n—F—X(ORF)m]z (3), these salts of weakly coordinating anions and use thereof.
Claims19
A method for preparing salts of weakly coordinating anions of the type corresponding to the following formula (1), (2) or (3):
- M[F—X(ORF)m]z (1)
- M[(FRO)mX—F—X(ORF)m]z (2)
- M[(FRO)mX—F—X(ORF)n—F—X (ORF)m]z (3)
- wherein, in a first step an organyl compound of an element XRm is reacted with a partially or completely fluorinated alcohol FROH in an organic, aprotic solvent and then, in a second step, the resulting alkoxy compound of the element X(ORF)m is reacted with a suitable fluoride salt MyYz so as to abstract a fluoride ion, if necessary under XFm-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.

Salts of weakly coordinating anions corresponding to formula (3):
- M[(FRO)mX—F—X(ORF)n—F—X(ORF)m]z (3)
- 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,
- z is 1 or 2, provided that, if z is 1, M is a monovalent anion,
- and/or if z is 2, M is a bivalent anion, and
- wherein, if z is 1, M is selected from the group consisting of alkali metal ions, In+, Ti+, Ag+, Cu+, NR′4+, PR′4+, wherein R′ is, independently in each case, hydrogen, a linear or branched C1 to C20-alkyl radical or substituted or unsubstituted aryl radical, and imidazolium, or, if z is 2, M is selected from the group consisting of Ni2+, Cu2+, Zn2+, Pd2+, Rh2+, and Pt2+, and RF is selected from the group consisting of linear or branched, partially or completely fluorinated C1 to C10 alkyl groups, partially or completely fluorinated C6 to C20 aryl groups, and partially or completely fluorinated C3 to C10 cycloalkyl groups.
