1. A catalyst compound comprising a compound represented by the formula: where M is a Group 4, 5 or 6 transition metal; each X is, independently, a univalent C1 to C20 hydrocarbyl radical, a functional group comprising elements from Groups 13-17 of the periodic table of the elements, or X1 and X2 join together to form a C4 to C62 cyclic or polycyclic ring structure; R1 and R11 are C1-C10 hydrocarbyl radicals; R4 and R14 are C1-C10 hydrocarbyl radicals or fluorine; R6, R7, R8, R9, R10, R16, R17, R18, R19, and R20 are fluorine; each R2, R3, R5, R12, R13, R15, R21, and R22 is independently, a hydrogen, a C1-C40 hydrocarbyl radical, a functional group comprising elements from Group 13-17 of the periodic table of the elements, or two or more of R2, R3, R5, R12, R13, R15, R21, and R22 may independently join together to form a C4 to C62 cyclic or polycyclic ring structure, or a combination thereof; and Y is a divalent C1 to C20 hydrocarbyl radical.
