(トリハロメチル)ベンゼン誘導体は医農薬、機能性材料及びそれらの製造中間体として有用である。しかしながら、(トリハロメチル)ベンゼン誘導体の中で、(ジブロモフルオロメチル)ベンゼン誘導体はほとんど知られていない。従来、(ジブロモフルオロメチル)ベンゼン誘導体は、対応する(トリブロモメチル)ベンゼン誘導体をフッ化水素により臭素原子をフッ素原子で置換する方法(特許文献1)及び(トリフルオロメチル)ベンゼン誘導体を三臭化ホウ素によりフッ素原子を臭素原子で置換する方法(非特許文献1)で製造されている。また、(ブロモフルオロメチル)ベンゼン誘導体の臭素化反応により(ジブロモフルオロメチル)ベンゼン誘導体を製造する方法が開示されている(非特許文献2)。しかしながら、何れの方法も過酷な反応条件が必要であり、基質一般性の低い方法である。また、(トリハロメチル)ベンゼン誘導体である(ブロモクロロフルオロメチル)ベンゼン誘導体及びその製造方法もこれまでほとんど報告されていない。
これまでに、アリールマグネシウム試薬とジブロモジフルオロメタンをハロゲン化アルカリ金属塩又はハロゲン化マグネシウム存在下反応させて、(ブロモクロロフルオロメチル)ベンゼン誘導体及び(ジブロモフルオロメチル)ベンゼン誘導体を得る製造法は全く報告されていない。
(Trihalomethyl) benzene derivatives are useful as medical pesticides, functional materials and production intermediates thereof. However, among (trihalomethyl) benzene derivatives, (dibromofluoromethyl) benzene derivatives are hardly known. Conventionally, (dibromofluoromethyl) benzene derivatives are obtained by replacing the corresponding (tribromomethyl) benzene derivative with hydrogen fluoride to replace bromine atoms with fluorine atoms (Patent Document 1) and (trifluoromethyl) benzene derivatives with three odors. It is manufactured by a method (Non-patent Document 1) in which a fluorine atom is substituted with a bromine atom by boron bromide. In addition, a method for producing a (dibromofluoromethyl) benzene derivative by bromination reaction of a (bromofluoromethyl) benzene derivative is disclosed (Non-Patent Document 2). However, each method requires harsh reaction conditions and is a method with low substrate generality. Also, there have been few reports on (bromochlorofluoromethyl) benzene derivatives which are (trihalomethyl) benzene derivatives and methods for producing the same.
So far, there has been no report on a process for producing (bromochlorofluoromethyl) benzene derivatives and (dibromofluoromethyl) benzene derivatives by reacting arylmagnesium reagents with dibromodifluoromethane in the presence of alkali metal halides or magnesium halides. It has not been.

An object of the present invention is to provide a method for producing a (trihalomethyl) benzene derivative useful as a medical pesticide, a functional material, and a production intermediate thereof, and a (trihalomethyl) benzene derivative having a high generality of substrate.
本発明者らは、上記課題を鑑み鋭意検討を重ねた結果、アリールマグネシウム試薬をハロゲン化アルカリ金属塩又はハロゲン化マグネシウム存在下、ジブロモジフルオロメタンと反応させることにより、(トリハロメチル)ベンゼン誘導体を簡便に製造できることを見出し、本発明を完成するに至った。
