Definitions
- This invention relates to highly active and stable ruthenium or osmium metal carbene complex compounds, synthesis methods thereof and their use as catalysts in olefin metathesis reactions.
- the present invention relates to ruthenium or osmium carbene compounds which are stable in the presence of a variety of functional groups and which can be used to catalyze olefin metathesis reactions on unstrained cyclic and acyclic olefins.
- the present invention relates to carbene compounds of the formula
- M is Os or Ru
- R and R 1 are independently selected from hydrogen or a hydrocarbon selected from the group consisting of C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 2 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 2 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl;
- X and X are independently selected from any anionic ligand
- L and L 1 are independently selected from any neutral electron donor, preferably phosphine, sulfonated phosphine, phosphite, phosphinite, phosphonite, arsine, stibine, ether, amine, amide, sulfoxide, carboxyl, nitrosyl, pyridine and thioether, most preferably trialkylphosphine ligands where at least one of the alkyl groups is a secondary alkyl or a cycloalkyl.
- the hydrocarbon is selected from the group consisting of C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy and a phenyl group.
- the hydrocarbon also may be substituted with a C 1 -C 5 alkyl halogen, C 1 -C 5 alkoxy, or a phenyl group.
- the phenyl group is optionally substituted with halogen, C 1 -C 5 alkyl or C 1 -C 5 alkoxy.
- all of the alkyl groups of the trialkyl phosphine are either a secondary alkyl or a cycloalkyl.
- the alkyl groups are either isopropyl, isobutyl, sec-butyl, neopentyl, neophenyl, cyclopentyl or cyclohexyl.
- L and L 1 ligands are alkyl phosphines where the carbon backbone of at least one alkyl group of the alkyl phosphine is a secondary alkyl or cycloalkyl have been found to possess higher metathesis activity, enabling these compounds to coordinate to and catalyze metathesis reactions between all types of olefins.
- previous metathesis catalysts were only able to catalyze metathesis reactions involving highly strained olefins.
- a broad array of metathesis reactions are enabled using the carbene compounds of the present invention that cannot be performed using less reactive catalysts.
- the present invention also relates to the synthesis of ruthenium or osmium carbene compounds which can be used to catalyze olefin metathesis reactions.
- carbene compounds of the present invention are the only Ru and Os carbene complexes known to date in which the metal is formally in the +2 oxidation state, have an electron count of 16, and are pentacoordinate. Unlike most metathesis catalysts presently known which are poisoned by functional groups, the carbene compounds of the present invention are stable in the presence of alcohol, thiol, ketone, aldehyde, ester, ether, amine, amide, nitro acid, carboxylic acid, disulfide, carbonate, carboalkoxy and halogen functional groups and may therefore be used in protic or aqueous solvent systems.
- the carbene compounds can be in the form wherein 2, 3 or 4 of the moieties X, X , L, and L can be taken together to form a chelating multidentate ligand.
- X, L, and L can be taken together to form a cyclopentadienyl, indenyl, or fluorenyl moiety.
- the ruthenium or osmium carbene compounds may be prepared by reacting a compound of the formula (XX 1 ML n L 1 m ) p , in the presence of solvent, with a cyclopropene of the formula
- p is an integer equal to or greater than 1
- R 2 and R 3 are independently selected from hydrogen or a hydrocarbon selected from the group consisting of C 2 -C 18 alkyl, C 2 -C 18 alkenyl, C 2 -C 18 alkynyl, C 2 -C 18 alkoxycarbonyl, aryl, C 1 -
- C 18 carboxylate C 1 -C 18 alkenyloxy, C 2 -C 18 alkynyioxy, C 1 -C 18 alkoxy, aryloxy, C 1 -C 18 alkylthio, C 1 -C 18 alkylsulfonyl or C 1 -C 18 alkylsulfinyl;
- the hydrocarbon is substituted with C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy or with a phenyl group.
- phenyl group is substituted with halogen, C 1 -C 5 alkyl or C 1 -
- X, L, and L are taken together to form a moiety selected from the group consisting of cyclopentadienyl, indenyl or fluorenyl, each optionally substituted with hydrogen; C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyioxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl, C 1 -C 20 alkylsulfinyl; each optionally substituted with C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy or with a phenyl group optionally substituted with halogen, C 1 -C
- a further method of preparing the compounds of this invention comprises reacting compound of the formula (XX 1 ML n L 1 m ) p in the presence of solvent with a phosphorane of the formula

- the solvent is then removed in vacuo to give a solid.
- This solid is then washed with a solvent in which the by-product of the reaction is soluble but the desired product is not. After the washing the product, the supernatant is removed and the resulting solid powder is dried in vacuo overnight. Further purification via crystallization can be performed if necessary.
- Methylene chloride (10 mL) was added to dissolve the complex.
- AgCF 3 CO 2 (24.9 mg., 1 equiv) was weighed into a 10 ml round-bottom flask, dissolved with 3 ml of THF. Both flasks were then capped with rubber septa and removed from the box. The Schlenk flask was then put under an argon atmosphere and the AgCF 3 CO 2 solution was added dropwise to this solution via a gas-tight syringe over a period of 5 min while stirring.
- the Schlenk flask was then put under an argon atmosphere and the AgCF 3 CO 2 solution was added dropwise via a gas tight syringe over a period of 5 min to the solution of ruthenium compound while stirring. At the end of the addition, there was a lot of precipitate in the reaction mixture and the solution turned into a fluorescent lime green color. The supernatant was transferred into another 50 mL Schlenk flask under argon atmosphere with the use of a cannula filter. Subsequent solvent removal in vacuo and washing with pentane (10 mL) afforded the above depicted compound as a green powder.
- the crude product was extracted with diethyl ether; volatiles were removed from the filtrate under vacuum to afford a dark colored, oily solid.
- the crude product was further extracted with petroleum ether; volatiles were removed from the filtrate under vacuum to afford a very dark red-brown oil. Recrystalization from petroleum ether at -40°C afforded dark crystals.
