    摘要： 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. Moreover, the present invention relates to a method for producing a cinnamic acid by letting a benzylidene diacetate react in the presence of a basic catalyst. The alkyl group substituted aromatic compounds acyloxylated and diacyloxylated at the side chain obtained in the present invention are useful for perfumes, and the benzyl alcohols and benzaldehydes obtained by hydrolyzing them are useful for intermediate products of agricultural chemicals, drugs and perfumes and also for resin additives. The cinnamic acids produced according to the present invention are useful for intermediate products of agricultural chemicals, drugs and perfumes.

    摘要： A method of selectively oxidizing an organic compound in a single vessel comprises: a) combining an organic compound, an acid solution in which the organic compound is soluble, a compound containing two oxygen atoms bonded to one another, and a metal ion reducing agent capable of reducing one of such oxygen atoms, and thereby forming a mixture; b) reducing the compound containing the two oxygen atoms by reducing one of such oxygen atoms with the metal ion reducing agent to, 1) oxidize the metal ion reducing agent to a higher valence state, and 2) produce an oxygen containing intermediate capable of oxidizing the organic compound; c) reacting the oxygen containing intermediate with the organic compound to oxidize the organic compound into an oxidized organic intermediate, the oxidized organic intermediate having an oxidized carbon atom; d) reacting the oxidized organic intermediate with the acid counter ion and higher valence state metal ion to bond the acid counter ion to the oxidized carbon atom and thereby produce a quantity of an ester incorporating the organic intermediate and acid counter ion; and e) reacting the oxidized organic intermediate with the higher valence state metal ion and water to produce a quantity of alcohol which is less than the quantity of ester, the acid counter ion incorporated in the ester rendering the carbon atom bonded to the counter ion less reactive with the oxygen containing intermediate in the mixture than is the alcohol with the oxygen containing intermediate.

    摘要： A process is provided for oxygenating alkyl-substituted aromatic compounds. In the process alkyl-substituted aromatic compounds are contacted with molecular oxygen in the presence of a suitable monocarboxylic acid, a soluble copper, cobalt, or iron compound, and an inorganic bromine compound. Optionally present are inorganic nitrates, acetic anhydride, or water. In an embodiment of the invention the process is carried out in two distinct steps with contact of the alkyl-substituted aromatic compounds and oxygen in the presence of the essential components produce an ester comprising both an aromatic alcohol and the carboxylic acid with subsequent hydrolyzing of this ester to produce an aromatic alcohol with regeneration of the carboxylic acid.
