Polydentate heteroatom ligand containing metal complexes, catalysts and methods of making and using the same

A composition comprising the reaction product or mixture resulting from contacting a ligand source characterized by the formula:

• wherein LG is a leaving group having up to 10 atoms;
• Y1, Y2, Y3 and Y4 is each independently selected from the group consisting of oxygen, phosphorus and sulfur;
• Z is a divalent group having up to 50 atoms, not counting hydrogen atoms;
• each AR is a divalent aromatic group of up to 50 atoms, not counting hydrogen atoms;
• each T is a group having up to 30 atoms total of the general formula —(CR202-x″)x′—, wherein each R20 substituent is independently selected from the group consisting of hydrogen, halogen, hydrocarbyl, inertly substituted hydrocarbyl, and groups of the formula:
• Q(R21)y, wherein R21 is hydrogen, halogen, hydrocarbyl, or inertly substituted hydrocarbyl, Q is O, P, S, N, Si or B, and y is an integer from 1 to 3 equal to one less than the valence of Q;
• x′ is 1 or 2;
• and x″ is 0 or 1;
• and optionally two or more R20 substituents may be joined into a ring- or multiring-structure having from 3 to 30 atoms, provided that said ring structure is not an aromatic group;
• with a metal compound corresponding to the formula:
• M(L)n′, or a dimeric or higher order derivative thereof, where
• M is a Group 3-6 or Lanthanide metal;
• each L is a neutral, monovalent or divalent ligand containing up to 50 atoms not counting hydrogen;
• and
• n′ is a number from 3 to 8.
