  • Publication number: 20020115885
    Abstract: Polyhalogenated cinnamic acids and cinnamic acid derivatives are prepared by reacting diazonium salts accessible from polyhalogenated anilines with acrylic acid or acrylic acid derivatives in the presence of a homogeneous, palladium-containing catalyst at about −5 to about +100° C. Some of the cinnamic acids and cinnamic acid derivatives obtainable in this way are new. Cinnamic acids and cinnamic acid derivatives which can be prepared according to the invention can be used for the preparation of indanones which are precursors for agro- and pharmaceutical chemicals and for substances having liquid-crystalline properties.

  • Patent number: 6278019
    Abstract: The present invention is a method for acyloxylating an alkyl group substituted aromatic compound at the side chain, by letting the alkyl group substituted aromatic compound and a carboxylic acid and/or a carboxylic anhydride react with each other in the presence of an oxygen containing gas. In this case, if (1) a solid catalyst in which at least one selected from cobalt, cerium and manganese is supported on a solid material or (2) a catalyst containing at least one selected from cobalt oxides, cerium oxides and manganese oxides is used, an alkali group substituted aromatic compound and a carboxylic acid and/or a carboxylic anhydride can be caused to react with each other efficiently in the presence of an oxygen containing gas, and in addition the catalyst can be easily separated from the reaction solution. Furthermore, (3) a compound diacyloxylated at the side chains can be highly selectively produced if a cerium compound is used as a catalyst in the absence of a cobalt compound and a manganese compound.
