Abstract
A compound comprising a polyfluorinated anion and the use thereof is provided. Specifically, the present invention provides a compound comprising an anion which comprises a polyfluorinated alkoxide coordinated to a transition metal, or a Group III, IV or V element.
Claims29
A compound comprising a monoanion of the formula:
- wherein
- M1 is a transition metal, or a Group III, IV or V element provided M1 is not Cu;
- each Z is independently O, S, or NR6R7;
- each X is independently a halide;
- each R1 is independently a bond or C1-C4 alkylene;
- each of R2, R3 and R4 is independently H, F, fluorinated C1-C10 alkyl, fluorinated C4-C20 aryl, C3-C10 cycloalkyl, fluorinated C3-C10 cycloalkyl, C1-C10 alkyl or C4-C20 aryl, provided at least one of R2, R3 and R4 is F, fluorinated C1-C10 alkyl, fluorinated C3-C10 cycloalkyl, or fluorinated C4-C20 aryl;
- each R5 is independently fluorinated C1-C10 alkyl, fluorinated C4-C20 aryl, C4-C20 aryloxide, fluorinated C4-C20 aryloxide, C1-C10 alkoxide or fluorinated C1-C10 alkoxide;
- each of R6 and R7 is independently H or C1-C10 alkyl;
- and
- each of a, b and c is independently an integer from 0 to 4,
- provided the sum of a, b and c is an integer from 2 to 8;
- and provided that when R2 is a fluorinated C1-C4 alkyl, R1 is a bond, b, and c are 0, and R3 is C1-C10 alkyl or fluorinated C1-C10 alkyl then R4 is F, fluorinated C1-C10 alkyl or fluorinated C4-C20 aryl.
