  The current invention provides novel bifunctional catalysts. The bifunctional catalysts are prepared from phosphine ligands and a cyclopentadienyl metal complex and are useful for forming isomers of hydrocarbon species. The hydrocarbon can be an alkenol having the alkene and alcohol groups far apart and the catalyst will move the double bond across numerous carbon atoms. The hydrocarbon can also be an achiral alkenol and the catalyst will form a chiral alcohol therefrom. Moreover, deuterated water may be added to the isomerization reaction mixture for forming deuterated hydrocarbon species.

  本发明提供了新型的双功能催化剂。这些双功能催化剂由膦配体和环戊二烯基金属配合物制备而成，可用于形成烃种类的异构体。烃可以是烯醇，其烯烃和羟基远离，催化剂将使双键移动到许多碳原子上。烃也可以是非手性烯醇，催化剂将形成手性醇。此外，可以向异构化反应混合物中添加氘化水以形成氘代烃种类。
• CATALYSTS FOR ALKENE ISOMERIZATION AND CONJUGATING DOUBLE BONDS IN POLYUNSATURATED FATS AND OILS

  The invention provides ruthenium-comprising catalysts, and methods of making and using them, for conjugating double bonds in polyunsaturated hydrocarbons, including polyunsaturated fatty acid derivatives, such as natural fats and oils which comprise (contain) more than one carbon to carbon double bond—where the double bonds are separated by, e.g., a methylene, ethylene or propylene or longer group. The invention provides compositions and methods for treating fats and oils comprising “interrupted” (e.g., “methylene-, ethylene- or propylene-interrupted”) double bonds to generate isomers with “conjugated” double bonds. The invention also provides compositions, and methods of making and using them, for making catalysts on a solid support. In one aspect, these catalysts are for alkene isomerization or exchange of alkene hydrogens for other isotopes. The invention provides heterocyclic resin-based compositions, and methods of using them, for making catalysts for alkene isomerization and exchange of hydrogens for deuterium or tritium isotopes.

  The invention provides ruthenium-comprising catalysts, and methods of making and using them, for conjugating double bonds in polyunsaturated hydrocarbons, including polyunsaturated fatty acid derivatives, such as natural fats and oils which comprise (contain) more than one carbon to carbon double bond - where the double bonds are separated by, e.g., a methylene, ethylene or propylene or longer group. The invention provides compositions and methods for treating fats and oils comprising 'interrupted' (e.g., 'methylene-, ethylene- or propylene- interrupted') double bonds to generate isomers with 'conjugated' double bonds. The invention also provides compositions, and methods of making and using them, for making catalysts on a solid support. In one aspect, these catalysts are for alkene isomerization or exchange of alkene hydrogens for other isotopes. The invention provides heterocyclic resin-based compositions, and methods of using them, for making catalysts for alkene isomerization and exchange of hydrogens for deuterium or tritium isotopes.
