Process for production of alkoxycarbonylthioaryl compounds

摘要

The present invention provides: a process for producing an alkali metal salt of an arylmercaptan compound, represented by general formula (3): which process comprises reacting a disulfide compound represented by general formula: with a hydroxide of an alkali metal M<1> in the presence of a sulfur compound represented by general formula (2): H(2-i)S(M<1>)i a process for producing an alkoxycarbonylalkylthioaryl compound represented by general formula (5): which process comprises reacting the above-mentioned alkalimetal salt of an arylmercaptan compound with a halogenofattyacid ester compound represented by general formula (4): X<1>R<2>COOR<3> at pH 7-10; and a process for producing the above-mentioned alkoxycarbonylalkylthioaryl compound, which process comprises reacting the above-mentioned disulfide compound with the above-mentioned hydroxide of an alkali metal M<1> in the presence of the above-mentioned sulfur compound to obtain an alkali metal salt of an arylmercaptan compound, and reacting said alkali metal salt, without isolating it, with the above-mentioned halogenofatty acid ester compound under the same condition as mentioned above.
