Description

本発明は、ペルフルオロ有機基を含有する有機化合物(ペルフルオロ有機物)の製造方法に関する。ペルフルオロ有機物は化学品、医農薬、樹脂等の中間体として有用な化合物である。特に置換可能な官能基が結合した炭化水素部位を有するペルフルオロ有機物は機能性材料を製造するためのモノマー成分として有用な化合物である。   The present invention relates to a method for producing an organic compound (perfluoro organic substance) containing a perfluoro organic group. Perfluoro organic substances are useful compounds as intermediates for chemicals, medical pesticides, resins and the like. In particular, a perfluoro organic substance having a hydrocarbon moiety to which a substitutable functional group is bonded is a useful compound as a monomer component for producing a functional material.

ペルフルオロ有機基を有機化合物に導入する手法としては、ラジカル開始剤存在下、ペルフルオロ有機ハロゲン化物とオレフィン化合物を反応させる手法が知られている。(特許文献1、非特許文献1参照)
しかし、これらの手法ではヨウ素や臭素などのハロゲン付加体で得られるため、さらに脱ハロゲン化の工程が必要となる。
As a technique for introducing a perfluoro organic group into an organic compound, a technique of reacting a perfluoro organic halide with an olefin compound in the presence of a radical initiator is known. (See Patent Document 1 and Non-Patent Document 1)
However, since these methods can be obtained with a halogen adduct such as iodine or bromine, a further dehalogenation step is required.

脱ハロゲン化としては、水素化アルミニウムリチウム、水素化トリブチルスズ、パラジウム(0)などの還元剤を用いる手法、またはニッケルやパラジウム等の金属触媒による接触水素化還元などが知られている。(非特許文献2参照)
また、合成中間体としてハロゲン付加体を経ない手法も報告されているが、純粋な一工程とはいえないし、やはり水素化トリブチルスズ等の還元剤が必須である。(非特許文献3、4参照)
As the dehalogenation, a method using a reducing agent such as lithium aluminum hydride, tributyltin hydride, palladium (0), or catalytic hydrogenation reduction using a metal catalyst such as nickel or palladium is known. (See Non-Patent Document 2)
In addition, although a method without a halogen adduct has been reported as a synthetic intermediate, it is not a pure one step, and a reducing agent such as tributyltin hydride is essential. (See Non-Patent Documents 3 and 4)

しかし、還元剤として用いられる水素化アルミニウムリチウムや水素化トリブチルスズは危険性や毒性が非常に高く、工業化にあたっては設備費も増大するなどの不利がある。さらに反応の際に生じるアルミニウム化合物やスズ化合物を廃棄する際には環境面および安全面に対して十分な注意が必要となる。
また、接触水素化還元ではニッケルやパラジウムなどの高価な貴金属触媒を使用するため、工業化する場合には触媒の回収が必要になるという欠点もある。
However, lithium aluminum hydride and tributyltin hydride used as a reducing agent are extremely dangerous and toxic and have disadvantages such as increased equipment costs for industrialization. Furthermore, when disposing of aluminum compounds and tin compounds generated during the reaction, sufficient attention must be paid to the environment and safety.
In addition, since catalytic hydrogenation reduction uses an expensive noble metal catalyst such as nickel or palladium, there is also a disadvantage that the catalyst must be recovered when industrialized.
