Abstract:
1. A method for producing a pentafluorosulfanylbenzoic acid, comprising: (A) a providing step of providing a trihalomethyl(pentafluorosulfanylbenzene) represented by general formula (1): where X is a halogen atom, n is an integer of 1≦n≦3, and the hydrogen atoms on the benzene ring are optionally replaced with a group having an oxygen atom, a group having a nitrogen atom, or a halogen atom; (B1) a step of reacting the trihalomethyl(pentafluorosulfanylbenzene) with a carboxylic acid, water, or a disiloxane represented by general formula (b): (where R is an alkyl group) in the presence of an acid other than carboxylic acids to form a pentafluorosulfanylbenzoic halide represented by general formula (2a): where X and n are as defined above, and the hydrogen atoms on the benzene ring are optionally replaced with the group or atom defined above; and (B2) a step of converting the pentafluorosulfanylbenzoic halide into a pentafluorosulfanylbenzoic acid represented by general formula (2): where n is as defined above, and the hydrogen atoms on the benzene ring are optionally replaced with the group or atom defined above.
