    摘要: The invention relates to a new compound (3-Vinylphenyl)phenylmethane,and a method for producing α-(3-benzoylphenyl)propionic acid of ketoprofen without difficulty at low cost and in a high yield. The method comprises the steps of: reacting (3-vinylphenyl)phenyl­methane with carbon monoxide and hydrogen, water or lower alcohol in the presence of a transition metal carbonylation catalyst to form α-(3-benzylphenyl)propionic acid deriva­tive, and when the thus obtained compound is an aldehyde, oxidizing methylene group and formyl group of the compound simultaneously or sequentially, or when the obtained compound is an acid or its ester, oxidizing the methylene group of the compound, and if necessary performing a hydrolysis step.

    摘要: A method for producing efficiently a highly pure 1-(m-ethylphenyl)-1-phenylethane or m-ethylphenylphenyl­methane which are used as the starting materials for preparing medicines and other organic compounds. The method comprises the step of reacting a diaryl compound with benzene or alkylbenzene in the presence of an acid catalyst selected from the group consisting of AlCl₃, AlBr₃, HF·BF₃ complex and Y-type zeolites.
