  • Patent number: 7858787
    Abstract: A process for converting an olefin having x carbon atoms into an olefin having x+1 carbon atoms wherein the process comprises the steps of: (i) reacting an olefin having x carbon atoms with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to produce an alcohol having x+1 carbon atoms, and (ii) dehydrating the alcohol produced in step (i) in the presence of a dehydration catalyst to produce an olefin having x+1 carbon atoms characterized in that the hydroformylation catalyst used in step (i) is based on: (a) a source of cobalt, and (b) a ligand which contains phosphorus and nitrogen.

  • Patent number: 7842845
    Abstract: In a process for the preparation of ring compounds via a combinatorial synthesis, the reaction procedure is based on a Suzuki coupling, subsequent halo-demetallation and finally a further Suzuki coupling. The Suzuki couplings are each carried out with a boronic acid or a boronic acid ester. The reaction procedure uses provides novel ring compounds and uses novel synthesis units used for this purpose. The novel ring compounds are suitable for use as constituents in liquid-crystalline mixtures.
