Definitions
- Imine complexes of certain transition metals such as iron, palladium, cobalt, nickel and others are important parts of catalyst systems for the polymerization of olefins, see for instance U.S. Patent 5,714,556, World Patent Applications 96/23010, 97/48737, 97/48735, 97/38024, and U.S. Patent Application 08/991372, filed Dec. 16, 1997 all of which are hereby included by reference.
- These and other references generally describe the synthesis of these types of imine complexes as the reaction of the imine containing ligand with various types of transition metal compounds to form the transition metal imine complex.
- These methods usually involve the use of substantially anhydrous conditions to avoid hydrolysis of the starting transition metal compound and/or any intermediates or the desired final complex.
- the imines themselves are not commercially available, usually being made from the corresponding carbonyl compound, such as a ketone or aldehyde, and an amine, often an aromatic amine.
- water is a byproduct. Since this imine forming reaction is usually considered to be an equilibrium, to drive the reaction to completion the water is often removed during the synthesis of the imine, for example by distillation, preferably azeotropic distillation, or by formation of a hydrate, preferably an inorganic hydrate.
- imine complexes of transition metals are often made in two step processes, imine synthesis, and then synthesis of the metal complex. A simpler, especially one step, synthesis would be preferable if they used the same starting materials since they would usually be cheaper than a two step synthesis.
- This invention concerns a process for the production of a transition metal complex of an imine, comprising, contacting under imine forming conditions in an aprotic solvent, a transition metal compound, a first organic compound containing at least one aldehyde or ketone group, and a second organic compound which is a primary amine to form said transition metal complex of said imine, and provided that said transition metal is nickel, palladium, iron and cobalt.
- imines can be made by the reaction of a carbonyl group such as a ketone or aldehyde with a primary amine, the reaction being: -NH, NR 1 + H 2 0 (1)
- (1) Since (1) is generally thought of as being an equilibrium reaction, it is usually driven to completion (formation of the imine) by removing the byproduct water that is formed. This can be done in a variety of ways, for instance removing the water by azeotropic distillation or as a hydrate of an inorganic salt.
- removing the water by azeotropic distillation or as a hydrate of an inorganic salt In order to efficientlky utilize carbonyl compound and amine used in (1), they should preferably be present in the reaction in approximately the same ratio as they are in the product.
- imine complexes [the imine (s) in the complex may contain one or more imine groups] of certain transition metals can be made in an aprotic solvent by addition of salts of those metals to a process in which reaction (1) is being carried out, even though water is generated as a byproduct.
- reaction (1) is carried out in the presence of a suitable salt of the desired transition metal.
- the ratio of transition metal salt to the other ingredients is not critical, but in order to efficiently utilize all of the ingredients the ratio of moles transition metal compound to moles of the other reactants is such that they are approximately the same as they are in final desired imine complex.
- the transition metal compound is preferably present at the beginning of the process, but may be added at any time during the formation of the imine.
- Useful transition metal compounds include metal halides, especially chlorides and bromides, and carboxylates. Zerovalent metal compounds that are not too sensitive to water may be used in conjunction with a suitable oxidizing agent (which are known in the art) . Preferred transition metal compounds are halides, especially chlorides and bromides.
- Transition metals are those metals in Groups 3-12 (IUPAC notation) , and metals in Groups 3-11 are preferred ana metals in Groups 8-10 are especially preferred. Specific preferred transition metals are nickel, cobalt, iron and palladium, and nickel is especially preferred.
- Preferred primary amines in the process are aryl amines, i.e., R is an aryl or substituted aryl group.
- Aryl herein includes groups that have one or more aromatic rings which may be fused, as in naphthyl, or connected by a- covalent bond, as in 2-phenylphenyl (o-biphenylyl) . It is preferred that the aromatic rings of the aryl group are carbocyclic rings, and it is more preferred that R 1 is phenyl or substituted phenyl.
- Useful substitutents on a substituted phenyl group are alkyl, especially alkyl containing 1 to 4 carbon atoms, halo, especially chloro, phenyl, and halo substituted alkyl, especially fluoro substituted alkyl. It is also preferred that the phenyl group be substituted in the 2, or 2 and 6, positions.
- aprotic the solvent has no protons whose pKa is about 20 or more, more preferably about 25 or more.
- Useful solvents include aromatic hydrocarbons such as benzene and toluene, xylene, chlorobenzene and o-dichlorobenzene . Since the transition metal complex may often be used in conjunction with other types of compounds (such as alkyl aluminum compounds) as a catalyst system for the polymerization of olefin, the absence of protic solvents is an advantage, since the solvent need not be removed before adding an alkyl aluminum compound.
- the carbonyl compound may contain more than one carbonyl group which may form an imine.
- Useful carbonyl compounds include ⁇ , ⁇ -diones, 2 , 6-pyridinedicarboxyaldehydes , 2 , 6-diacylpyridines , cyclic ⁇ , ⁇ -diones, 1,3-diones and ketoaldehydes .
- Specific useful carbonyl compounds include glyoxal, 2, 3-butanedione, acenapthenequinone, 2, 6-diacetylpyridine, 2, 6-pyridinedicarboxaldehyde, 1, 2-cyclohexanedione, and pyruvaldehyde .
- the transition metal imine complex after it is made, may be isolated, as by removing the solvent under vacuum or by crystallization, or the solution may be used directly (i.e., without isolation of the complex, but the solution may be filtered to remove any insoluble impurities) in a polymerization of one or more olefins.
- Olefins which may be polymerized with various transition metal complexes of imines, and the conditions for polymerizations will be found in U.S. Patent 5,714,556, World Patent Applications 96/23010, 97/48737, 97/48735, 97/38024, and U.S. Patent
- Nickel dibromide was purified of insoluble material by dissolving 2.22 g anhydrous nickel dibromide in 100 mL ethanol containing 1 mL water, filtering through diatomaceous earth and rotary evaporating dry. A mixture of 1.84 g (10.1 mmol) acenapthenequinone, 3.00 g (20.0 mmol) 2, 6-diethylaniline, 2.1 g (9.6 mmol) nickel dibromide and 50 mL toluene was refluxed under nitrogen with water removal for 24 h to give a deep red-black reaction mixture.
- Example 2 A suspension of 2.0 mg (0.0030 mmol) (I) of Example 1 in 5 mL dry, deaerated toluene was mixed with 1.0 mL 1.7M modified methylaluminoxane in toluene
- Example 4 A mixture of 20 mL dry, deaerated toluene and
- the ethylene was vented and the solution was stirred with 25 mL 6N HCl and 20 mL additional toluene, and the toluene layer was separated, water-washed and rotary-evaporated to yield, after washing with methylene chloride and acetone and vacuum-oven drying (70°C) , 0.96 g of soft, tacky polyethylene .
