Description
TECHNICAL FIELD

This invention relates generally to olefin metathesis catalysts, to the preparation of such compounds, compositions comprising such compounds, methods of using such compounds, and the use of such compounds in the metathesis of olefins and in the synthesis of related olefin metathesis catalysts. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and in industrial applications such as oil and gas, fine chemicals and pharmaceuticals.


BACKGROUND

Since its discovery in the 1950s, olefin metathesis has emerged as a valuable synthetic method for the formation of carbon-carbon double bonds. Recent advances in applications to organic syntheses and polymer syntheses mostly rely on developments of well-defined olefin metathesis catalysts.


The technology of ruthenium metathesis catalysts has enabled the development of several research platforms including: ring opening metathesis polymerization (ROMP), ring opening cross metathesis (ROCM), cross metathesis (CM), ring closing metathesis (RCM).


First Generation Grubbs ruthenium olefin metathesis catalysts, such as: (PCy3)2(Cl)2Ru═CHPh, have been largely used in organic synthesis.


The incorporation of certain types of N-Heterocyclic Carbene (NHC) ligands played an essential role in the development of ruthenium metathesis catalysts, giving rise to the Second Generation Grubbs ruthenium olefin metathesis catalysts, such as: (IMesH2)(PCy3) (Cl)2Ru═CHPh, where IMesH2 is 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene.


In order to exchange the phosphine on the Second Generation Grubbs ruthenium olefin metathesis catalysts, the Grubbs group reported in 2001 (Organometallics 2001, 20, 5314-5318) a method involving a precursor bearing two pyridine ligands: (IMesH2)(Cl)2(C5H5N)2Ru═CHPh. The labile pyridine ligands have allowed the preparation of diverse ruthenium olefin metathesis catalysts. However, the preparation of pyridine complexes, requires large quantities of expensive and malodorous reagents (pyridine), and difficult reaction conditions (negative ° C. temperatures) especially for industrial scale-up.


Therefore there is an ongoing need for efficient, high yield, high purity and ease in scaling up procedures for the synthesis of olefin metathesis catalysts, particularly Second Generation Grubbs ruthenium olefin metathesis catalysts.


SUMMARY OF THE INVENTION

To meet this need the inventors have discovered novel ruthenium olefin metathesis catalysts, bearing a sulfoxide ligand as described herein. The ruthenium olefin metathesis catalysts bearing sulfoxide labile ligands exhibit high stability and allow the ready synthesis of various Second Generation Grubbs ruthenium olefin metathesis catalysts in higher yield and with higher purity, compared to the existing procedures.

The metal carbene olefin metathesis catalysts can be utilized in olefin metathesis reactions according to techniques known in the art. For example, the metal carbene olefin metathesis catalysts are typically added to a resin composition as a solid, a solution, or as a suspension. When the metal carbene olefin metathesis catalysts are added to a resin composition as a suspension, the metal carbene olefin metathesis catalysts are suspended in a dispersing carrier such as mineral oil, paraffin oil, soybean oil, tri-iso-propylbenzene, or any hydrophobic liquid which has a sufficiently high viscosity so as to permit effective dispersion of the catalyst(s), and which is sufficiently inert and which has a sufficiently high boiling point so that is does not act as a low-boiling impurity in the olefin metathesis reaction. It will be appreciated that the amount of catalyst that is used (i.e., the “catalyst loading”) in the reaction is dependent upon a variety of factors such as the identity of the reactants and the reaction conditions that are employed. It is therefore understood that catalyst loading can be optimally and independently chosen for each reaction. In general, however, the catalyst will be present in an amount that ranges from a low of about 0.1 ppm, 1 ppm, or 5 ppm, to a high of about 10 ppm, 15 ppm, 25 ppm, 50 ppm, 100 ppm, 200 ppm, 500 ppm, or 1000 ppm relative to the amount of an olefinic substrate (e.g., cyclic olefins).

Such cyclic olefins may be optionally substituted, optionally heteroatom-containing, mono-unsaturated, di-unsaturated, or poly-unsaturated C5 to C24 hydrocarbons that may be mono-, di-, or poly-cyclic. The cyclic olefin may generally be any strained or unstrained cyclic olefin, provided the cyclic olefin is able to participate in a ROMP reaction either individually or as part of a ROMP cyclic olefin composition.

Experimental
General Information—Materials and Methods

In the following examples, efforts have been made to ensure accuracy with respect to numbers used (e.g., amounts, temperature, etc.) but some experimental error and deviation should be accounted for. The examples are to be considered as not being limiting of the invention described herein. Surprisingly, the olefin metathesis catalysts of the invention were obtained only in the cis configuration, no traces of the trans stereoisomers were detected.


All reactions involving metal complexes were conducted in oven-dried glassware under an argon or nitrogen atmosphere using standard Schlenk techniques. Chemicals and solvents were obtained from Sigma-Aldrich, Strem, Alfa Aesar, Nexeo, Brenntag, AG Layne and TCI. Commercially available reagents were used as received unless otherwise noted. Silica gel was purchased from Fisher (0.040-0.063 μm, EMD Millipore).


The crystallographic measurements were performed at 100(2) K using a Bruker APEX-II CCD area detector diffractometer (Mo—Kα radiation, λ=0.71073 Å). In each case, a specimen of suitable size and quality was selected and mounted onto a nylon loop. The structures were solved by direct methods, which successfully located most of the non-hydrogen atoms. Semi-empirical absorption corrections were applied. Subsequent refinement on F2 using the SHELXTL/PC package (version 6.1) allowed location of the remaining non-hydrogen atoms.


Ultrene® 99 dicyclopentadiene (DCPD) was obtained from Cymetech Corporation. A modified DCPD base resin containing 20-25% tricyclopentadiene (and small amounts of higher cyclopentadiene homologs) (DCPD-HT) was prepared by heat treatment of Ultrene® 99 DCPD generally as described in U.S. Pat. No. 4,899,005.


Catalysts C931, C933, C793, C827, C705, C727, C748 and C848 were prepared using known methods.



1H and 13C NMR spectra were recorded on a Varian 400 MHz spectrometer. Chemical shifts are reported in ppm downfield from Me4Si by using the residual solvent peak as an internal standard (CDCl3 δ 7.24 ppm). Spectra were analyzed and processed using MestReNova software.

Catalytic Activity of the Olefin Metathesis Catalysts of the Invention
Example 18
ROMP Reaction of DCPD-HT

The catalytic activity of the complexes according to the invention was evaluated in ROMP reactions as follows. A 250 mL beaker was filled with 100 g of DCPD-HT monomer and 50 ppm of CHP. The monomer was equilibrated to the desired temperature in an oil bath (30° C.+/−0.5° C.). A J-Type thermocouple was suspended directly into the center of the monomer. The catalyst under study was dissolved in solvent (either toluene or CH2Cl2) to form a catalyst solution and the catalyst solution was then added to the monomer at a molar ratio of 45,000:1 (monomer:catalyst) to form a ROMP composition. Addition of the catalyst to the monomer to form the ROMP composition denoted the start of the ROMP reaction and hence, this was time point zero. Temperature readings were recorded using the thermocouple. The exotherm time was determined by measuring the amount of time that passed (i.e., the time difference) between time point zero and the time point that a propagating interface of the ROMP composition was first visually observed as the ROMP composition transitioned from a liquid state or gel state to a cured polymer state. ROMP reactions were stopped 2 hours after addition of the catalyst solution to the monomer. Time to exotherm is expressed by: slow>120 minutes; moderate 30-120 minutes; medium 1-<30 minutes; fast<1 minute and peak exotherm temperature. The results are shown in Table (5).

Following the procedure outlined in Organometallics, 2006, 25, 5740-5745, inside an argon filled glovebox, a screwcap NMR tube fitted with a PTFE septum was charged with CD2Cl2 (0.75 mL or 0.775 mL) and catalyst stock solution (0.016 M, 50 μL, 0.80 μmol, 1.0 mol % or 0.016 M, 25 μL, 0.80 μmol, 0.5 mol %). Samples were equilibrated to 30° C. in a preheated NMR probe before diethyl 2,2-diallylmalonate (19.3 μL, 19.2 mg, 0.080 mmol, 0.1 M) was added via syringe. The ensuing reaction was monitored for 30 minutes using the Varian array function and the conversion to diethyl cyclopent-3-ene-1,1-dicarboxylate was determined by comparing the ratio of the integrals of the methylene protons in the starting material, δ 2.61 (dt), with those in the product, δ 2.98 (s). FIG. 3 shows the conversion of diethyl 2,2-diallylmalonate to 4,4-bis(ethoxy carbonyl)cyclopentene, wherein Catalyst is: C747, C748, C647, C773, C625, C727 or C705.
