    • The present invention lies in a process for producing a trifluoromethylthiomethylbenzene derivative represented by the following general formula (2): (wherein R is a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group, a cyano group, a nitro group, or a benzoyl group which may be substituted with halogen atom, alkyl group, alkoxy group, aliphatic or aromatic acyl group, nitro group, cyano group or alkoxycarbonyl group; n is an integer of 1 to 5; when n is an integer of 2 or more, a plurality of R's may be the same of each independently different), which process comprises reacting, in acetonitrile, a benzyl halide derivative represented by the following general formula (1): (wherein R and n have the same definitions as given above; and X is a halogen atom, an alkylsulfonyloxy group or an arylsulfonyloxy group which may be substituted with alkyl group or halogen atom) with thiophosgene and potassium fluoride.
    • 本发明在于制备由以下通式(2)表示的三氟甲硫基甲基苯衍生物的方法:其中R是氢原子,卤素原子,烷基,烷氧基,烷氧基羰基,氰基, 硝基或可被卤素原子,烷基,烷氧基,脂肪族或芳香族酰基,硝基,氰基或烷氧基羰基取代的苯甲酰基,n为1〜5的整数,n为1〜5的整数, 2个以上的整数,多个R可以各自独立地不同),该方法包括在乙腈中使由以下通式(1)表示的苄基卤衍生物:(其中R和n具有相同的 定义如上所述; X为卤素原子,烷基磺酰氧基或可被烷基或卤原子取代的芳基磺酰氧基)与硫光气和氟化钾反应。
