  • Method for producing unsaturated compounds
    Patent number: 9120736
    Abstract: The invention relates to a method for producing compositions containing unsaturated compounds, wherein (A) one or more unsaturated monocarboxylic acids having 10 to 24 C-atoms or esters of said monocarboxylic acids and optionally (B) one or more compounds having at least one C?C double bond (wherein the compounds (B) are different from the compounds (A)) are subjected to a tandem isomerization/metathesis reaction sequence in the presence of a palladium catalyst and a ruthenium catalyst, providing that the palladium catalysts used are compounds that contain at least one structural element Pd—P(R1R2R3), wherein the radicals R1 to R3, independently of one another, each comprise 2 to 10 C-atoms, which may be aliphatic, alicyclic, aromatic or heterocyclic respectively, providing that at least one of the radicals R1 to R3 contains a beta-hydrogen, wherein the palladium catalyst is used as such or is produced in situ, providing that the method is carried out in the absence of substances that have a pKa value of 3 or

  • Process for preparing aryl- and heteroarylacetic acid derivatives
    Patent number: 9096568
    Abstract: The invention relates to a process for preparing aryl- and heteroarylacetic acids and derivatives thereof by reaction of aryl or heteroaryl halides with malonic diesters in the presence of a palladium catalyst, of one or more bases and optionally of a phase transfer catalyst. This process enables the preparation of a multitude of functionalized aryl- and heteroarylacetic acids and derivatives thereof, especially also the preparation of arylacetic acids with sterically demanding substituents.

  • Method to prepare beta-functionalized aliphatic esters
    Patent number: 8877958
    Abstract: The invention pertains to a new route to prepare ?-functionalized carboxylic acid esters in a one-pot reaction, by reacting an olefinic acid ester in the presence of a catalyst system, comprising a Rh(I)-complex, together with an aryl boron or a diamine as nucleophilic compounds, and under oxygen-free conditions and elevated temperatures.

  • Process for preparing aryl- and heteroarylacetic acid derivatives
    Patent number: 8507688
    Abstract: The present invention relates to a process for preparing ?-arylmethylcarbonyl compound of the formula (III), characterized in that aryl- and heteroarylacetic acids and derivatives thereof of the formula (I) are reacted with ?-halomethylcarbonyl compounds of the formula (II) in the presence of a palladium catalyst, of a phosphine ligand, of an inorganic base and of a phase transfer catalyst, optionally using an organic solvent.
