Abstract:
A compound comprising a monoanion of the formula: whereinM1 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.
