Asymmetric Fluorenyl-Substituted Salan Catalysts

A catalyst compound represented by the Formula (I):

• wherein each solid line represents a covalent bond and each dotted line represents a bond having a varying degree of covalency and a varying degree of coordination;
• wherein M is a Group 3, 4, 5, or 6 transition metal;
• N1 and N2 are nitrogen;
• O is oxygen;
• each of X1 and X2 is, independently, a univalent C1 to C20 hydrocarbyl radical, a univalent substituted C1 to C20, or X1 and X2 join together to form a C4 to C62 cyclic or polycyclic ring structure, provided however when M is trivalent X2 is not present;
• each R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, and R*1, is, independently, hydrogen, a C1 to C40 hydrocarbyl radical, or a substituted C1 to C40 hydrocarbyl group;
• optionally, wherein two or more of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, and R21 may independently join together to form a C4 to C62 cyclic or polycyclic ring structure, or a combination thereof.
• wherein R*1 comprises a group other than a substituted or unsubstituted fluorenyl group;
• and
• wherein Y is a C1 to C40 divalent hydrocarbyl radical comprising a linker backbone comprising from 1 to 18 carbon atoms bridging between nitrogen atoms N1 and N2.
