Heterocyclic amido transition metal complexes, production and use thereof

A heterocyclic amido transition metal complex represented by the formula (A) or (B):

• wherein:
• M is a Group 3, 4, or 5 metal;
• Q1 is a group that links R2 and R3 by a three atom bridge represented by the formula:
• -G1-G2-G3- where G2 is a group 15 or 16 atom that forms a dative bond to M, G1 and G3 are each a group 14 atom that are joined together by two or three additional group 14, 15, or 16 atoms to form a heterocycle or substituted heterocycle;
• Q2 is a group that forms an anionic bond with M, said Q2 group being selected from O, S, CH2, CHR17, C(R17)2, NR17 or PR17, where each R17 is independently selected from hydrogen, halogen, hydrocarbyls, substituted hydrocarbyls, halocarbyls, substituted halocarbyls, silylcarbyls, and polar groups;
• Q3 is -(TT)- or -(TTT)-, where each T is a substituted or unsubstituted group 14, 15, or 16 element so that together with the “—C—N═C—” fragment it forms a 5- or 6-membered heterocycle or substituted heterocycle;
• R1 is selected from hydrocarbyls, substituted hydrocarbyls, halocarbyls, substituted halocarbyls, and silylcarbyls;
• R2 is -E(R12)(R13)— where E is carbon, silicon, or germanium, and each R12 and R13 is independently selected from the group consisting of hydrogen, halogen, hydrocarbyls, substituted hydrocarbyls, halocarbyls, substituted halocarbyls, silylcarbyls, substituted and polar groups;
• R3 is either C or N, and R4 and R5 are C, and R3 and R4 are part of a five or six-membered carbocyclic or heterocyclic ring, which may be substituted or unsubstituted, and R4 and R5 are part of a five or six-membered carbocyclic or heterocyclic ring, which may be substituted or unsubstituted;
• each J is independently selected from C, CH, CH2, CR18, CHR18, C(R18)2, Si(R18)2, SiH(R18), NH, NR18, O, or S, where R18 is selected from hydrocarbyls, substituted hydrocarbyls, halocarbyls, substituted halocarbyls, halogen, and silylcarbyls;
• each x is independently 3 or 4 representing the number of J groups linked together in series;
• Y is selected from substituted and unsubstituted group 14 elements;
• 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;
• L′ is neutral Lewis base;
• n is 1, 2, or 3;
• w is 0, 1, 2, or 3;
• wherein n+w is not greater than 4;
• and
• wherein the tridentate dianionic ligand is chelated to the metal M in such a fashion that the complex features an eight-membered chelate ring and a five-membered chelate ring, which are indicated in the formulas (A) and (B) by the numbers 8 and 5, respectively.
