M is a Group 3 or 4 metal; Q 1 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 R 30 group) represented by the formula: -G 1 -G 2 -G 3 - where G 2 is a group 15 or 16 atom (said group 15 element may be substituted with a R 30 group), G 1 and G 3 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 R 30 groups), where G 1, G 2 and G 3, or G 1 and G 2, or G 1 and G 3, or G 2 and G 3 may form a singular or multi ring system; each R 30 group is, independently, hydrogen or a C 1 to C 100 hydrocarbyl group or a silyl group; Q 2 is -NR 17 or -PR 17, where R 17 is selected from hydrocarbyls, substituted hydrocarbyls, silyls, and germyls; R 1 is selected from the group consisting of hydrocarbyls, and substituted hydrocarbyls, or silyl groups; R 3, R 4, and R 5 are independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, alkoxy, aryloxy, halogen, amino, and silyl, and wherein adjacent R groups (R 3 & R 4 and/or R 4 & R 5) 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; R 6, R 7, R 8, R 9, R 10, R 11, R 12, and R 13 are independently selected from the group consisting of hydrogen, hydrocarbyls, substituted hydrocarbyls, alkoxy, halogen, amino, and silyl, and wherein adjacent R groups (R 6 & R 7, and/or R 8 & R 9, and/or R 9 & R 10, and/or R 10 & R 11 and/or R 12 & R 13) 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; R 2 is -E(R 12)(R 13)- with E being carbon, silicon, or germanium; Y is selected from oxygen, sulfur, and -E ∗ (R 6)(R 7)-, with E ∗ being carbon, silicon, or germanium; 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 1 or 2; L' is neutral Lewis base; and w is 0, 1, 2, 3 or 4.
