Disclosed is a commercially suitable method for producing a 1-substituted-10-(4-halophenyl)decane with high yield in a short time without producing 4,4'-dichlorobiphenyl (an environmental pollutant). Also disclosed is a commercially suitable method for producing a 2,2-dichloro-12-(4-halophenyl)dodecanate salt with high yield by a simple process. Specifically disclosed is a method for producing a 1-substituted-10-(4-halophenyl)decane characterized by reacting a 4-halobenzylmagnesium halide with a 1,9-disubstituted nonane. Also specifically disclosed is a method for producing a 2,2-dichloro-12-(4-halophenyl)dodecanate salt characterized by comprising a first step for obtaining a 2,2-dichloro-12-(4-halophenyl)dodecanoic acid ester by reacting a 1-iodo-10-(4-halophenyl)decane and a dichloroacetic acid ester in the presence of a base, and a second step for converting the 2,2-dichloro-12-(4-halophenyl)dodecanoic acid ester into a 2,2-dichloro-12-(4-halophenyl)dodecanate salt. Further specifically disclosed are 1-iodo-10-(4-chlorophenyl)decane and a method for producing the same.
