Abstract

Embodiments of the present disclosure are directed towards metal complexes that can be utilized to form polymers. As an example, the present disclosure provides a metal complex of Formula (I) wherein M is Zr, Hf, or Ti; each Het is independently a heterocyclic; each L is independently a bridging group; each X is independently Cl, Br, I, or alkyl; each R 1 is independently selected from the group including hydrogen, alkyls, alkenyls, alkynyls, cycloalkyls, aryls, acyls, aroyls, alkoxys, aryloxys, alkylthiols, dialkylamines, alkylamidos, alkoxycarbonyls, aryloxycarbonyls, carbomoyls, alkyl- and dialkyl-carbamoyls, acyloxys, acylaminos, aroylaminos, aromatic rings, fused aromatic rings, and combinations thereof; and each n is independently an integer having a value of one to five.

First claim

What is claimed:

1. A metal complex of Formula II:

wherein the metal complex of Formula II is formed by reacting a metal complex of Formula I with a polar organic material selected from the group of ketones, aldehydes, imines, and combinations thereof; each A is independently O, S, or N—R 4 ; and each R 2 , R 3 and, R 4 are independently selected from the group including hydrogen, alkyls, alkenyls, alkynyls, cycloalkyls, aryls, acyls, aroyls, alkoxys, aryloxys, alkylthiols, dialkylamines, alkylamidos, alkoxycarbonyls, aryloxycarbonyls, carbomoyls, alkyl- and dialkyl-carbamoyls, acyloxys, acylaminos, aroylaminos, aromatic rings, fused aromatic rings, and combinations thereof or R 2 and R 3 are combined to be an oxo group, an alkylimino group, or a thio group, wherein the metal complex of Formula I is:

wherein M is Zr, Hf, or Ti; each Het is independently a heterocyclic; each L is independently a bridging group; each X is independently Cl, Br, I, or alkyl; each R1 is independently selected from the group including hydrogen, alkyls, alkenyls, alkynyls, cycloalkyls, aryls, acyls, aroyls, alkoxys, aryloxys, alkylthiols, dialkylamines, alkylamidos, alkoxycarbonyls, aryloxycarbonyls, carbomoyls, alkyl- and dialkyl-carbamoyls, acyloxys, acylaminos, aroylaminos, aromatic rings, fused aromatic rings, and combinations thereof; and each n is independently an integer having a value of one to five.

2. The metal complex of claim 1 , wherein M is Zr.

3. The metal complex of claim 2 , wherein each heterocyclic includes N.

4. The metal complex of claim 3 , wherein the polar organic material is a ketone.

5. The metal complex of claim 3 , wherein the ketone is acetone.

6. A supported metal complex comprising:
the metal complex of claim 1 ;
an activator; and
a support material.

7. A method for forming a metal complex comprising:
reacting an aryl-heteroaryl compound with a metal dihalide precursor to form a metal complex of Formula I:

wherein M is Zr, Hf, or Ti; each Het is independently a heterocyclic; each L is independently a bridging group; each X is independently Cl, Br, I, or alkyl; each R 1 is independently selected from the group including hydrogen, alkyls, alkenyls, alkynyls, cycloalkyls, aryls, acyls, aroyls, alkoxys, aryloxys, alkylthiols, dialkylamines, alkylamidos, alkoxycarbonyls, aryloxycarbonyls, carbomoyls, alkyl- and dialkyl-carbamoyls, acyloxys, acylaminos, aroylaminos, aromatic rings, fused aromatic rings, and combinations thereof; and each n is independently an integer having a value of one to five.

8. The method of claim 7 , wherein the metal dihalide is dibenzyldichlorozirconium etherate.

9. The method of claim 7 , futher comprising:
reacting the metal complex of claim 7 with a polar organic material selected from the group of ketones, aldehydes, imines, and combinations thereof to form a metal complex of Formula II:

wherein each A is independently O, S, or N-R 4 ; and each R 2 , R 3 and, R 4 are independently selected from the group including hydrogen, alkyls, alkenyls, alkynyls, cycloalkyls, aryls, acyls, aroyls, alkoxys, aryloxys, alkylthiols, dialkylamines, alkylamidos, alkoxycarbonyls, aryloxycarbonyls, carbomoyls, alkyl- and dialkyl-carbamoyls, acyloxys, acylaminos, aroylaminos, aromatic rings, fused aromatic rings, and combinations thereof or R 2 and R 3 are combined to be an oxo group, an alkylimino group, or a thio group.

10. The method of claim 9 , wherein the polar organic material is a ketone.

11. A method of forming a polymer comprising:
contacting an olefin with a metal complex of claim 1 .
