    摘要： Both low-molecular and high-molecular aromatic or heteroaromatic compounds, which are substituted with olefins, play an important role in industry, for example as auxiliary agents or additives in cosmetic preparations such as sunscreen agents, in diverse fine chemicals and chemicals for the electronics industry and in intermediate products for the pharmaceutical and agrochemical industries. Such compounds are of outstanding importance particularly in the rapid-growth field of organic semiconductors, (e.g. for use in organic or polymer LEDs, organic solar cells and organic integrated circuits). The invention relates to a method for producing olefin-substituted aromatic or heteroaromatic compounds of this type, by reacting a functional aryl or heteroaryl compound with an olefin derivative, which has at least one H-atom on its double bond, in the presence of a simple palladium compound, optionally in the presence of an additive containing nitrogen and of a base in a solvent, to form a C-C-linkage and a formal splitting-off of the aryl, or heteroaryl derivative functional group and of one H-atom of the olefin compound. The invention is characterised by the presence of at least one additive containing metal, which is different from palladium.

    摘要： A novel, improved process and catalyst are provided for the catalytic hydrodechlorination in the gaseous phase of a chlorinated alkane to its corresponding less-chlorinated and preferably non-chlorinated alkane, for example the hydrodechlorination of 1,2-dichloropropane to propane, the catalyst comprising a mixture of active Group VIII hydrogenating metals in elemental or compound form on a support.
