    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aromatic compound, capable of conducting an oxidative coupling reaction of starting aromatic compounds so as to effectively produce the aromatic compound having condensed rings corresponding to the starting aromatic compounds. SOLUTION: This method for producing the aromatic compound comprises contacting the starting aromatic compounds with molecular oxygen in the presence of catalysts, and making the starting compounds directly bond to each other through single bonds, so as to form the aromatic compound having the condensed rings corresponding to the starting aromatic compounds, wherein the catalyst is composed of (A) a palladium compound catalyst and (B) a catalyst comprising (B1) a heteropoly-acid or its salt or (B2) a mixture of oxoacids containing an element of P or Si, and at least one element selected from V, Mo, and W as a whole, or their salts.

    Abstract: PROBLEM TO BE SOLVED: To provide a ketone from the corresponding secondary alcohol at a high conversion and a high selectivity. SOLUTION: This ketone compound is obtained by oxidizing the corresponding secondary alcohol having at least secondary hydroxy group in the presence of a reducing inorganic compound or acid, with bromic acid or its salt, at >=40 deg.C to convert the secondary hydroxy group to oxo group. The ratio of the bromic acid or its salt is less than 1 chemical equivalent based on the secondary hydroxy group and the ratio of the reducing inorganic compound or acid is 0.01-0.9 chemical equivalent based on the bromic acid. When a polyhydric alcohol having a secondary hydroxy group and a primary hydroxy group (propylene glycol, glycerol or the like) is used as the alcohol, the corresponding hydroxyketone compound is produced. A sulfite, a hydrogensulfite, a pyrosulfite, a thiosulfate or the like can be used as the reducing inorganic compound.

    Abstract: PROBLEM TO BE SOLVED: To efficiently obtain the corresponding aldehyde by subjecting 1,2-diol to oxidative cleavage with oxygen. SOLUTION: 1,2-Diol (vic-diol) is reacted with oxygen in the presence of a support-carried type ruthenium catalyst. Thereby, two carbon atoms to which a hydroxyl group is bonded are oxidatively cleaved to produce the corresponding aldehyde. The support includes activated carbon. An organic ruthenium complex or the like such as dichlorotris(triphenyl phosphine) ruthenium (II) can be used as the catalyst component carried on the support.
