主权项 1. A pyridyldiamido transition metal complex represented by the formula: (A), (B), (C), or (D): wherein: M is a Group 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 metal; Q1 is a three atom bridge with the central of the three atoms being a group 15 or 16 element (said group 15 element may or may not be substituted with an R30 group) represented by the formula: -G1-G2-G3- where G2 is a group 15 or 16 atom (said group 15 element may be substituted with a R30 group), G1 and G3 are each a group 14, 15, or 16 atom (each group 14, 15, and 16 element may or may not be substituted with one or more R30 groups), where G1, G2 and G3, or G1 and G2, or G1 and G3, or G2 and G3 may form a singular or multi ring system; each R30 group is, independently, hydrogen or a C1 to C100 hydrocarbyl group or a silyl group; Q2 is —NR17, —PR17, or oxygen, where R17 is selected from hydrogen, hydrocarbyls, substituted hydrocarbyls, silyls, or germyls; Q3 is -(TT)- or -(TTT)- where each T is carbon or a heteroatom, and said carbon or heteroatom may be unsubstituted or substituted with one or more R30 groups that together with the “—C-Q3=C—” fragment, forms a 5- or 6-membered cyclic group or a polycyclic group including the 5 or 6-membered cyclic group; R1 is selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, and silyl groups; R3, R4, and R5 are independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, alkoxy, aryloxy, halogen, amino, and silyl, and wherein adjacent R groups (R3 & R4 and/or R4 & R5) may be joined to form a substituted or unsubstituted hydrocarbyl or heterocyclic ring, where the ring has 5, 6, 7, or 8 ring atoms and where substitutions on the ring can join to form additional rings; R2 is -E(R12)(R13)— with E being carbon, silicon, or germanium; Y is selected from oxygen, sulfur, or -E*(R6)(R7)—, with E* being carbon, silicon, or germanium; R6, R7, R8, R9, R10, R11, R12, and R13 are independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, alkoxy, halogen, amino, and silyl, and wherein adjacent R groups (R6 & R7, and/or R8 & R9, and/or R9 & R10, and/or R10 & R11 and/or R12 & R13) may be joined to form a saturated, substituted or unsubstituted hydrocarbyl or heterocyclic ring, where the ring has 5, 6, 7, or 8 ring carbon atoms and where substitutions on the ring can join to form additional rings; L is an anionic leaving group, where the L groups may be the same or different and any two L groups may be linked to form a dianionic leaving group; n is 0, 1, 2, 3, or 4; L′ is a neutral Lewis base; and w is 0, 1, 2, 3, or 4.
