Description
本発明は、医薬・農薬分野、または液晶等の電子材料分野で有用なトリフルオロメチルアレーン類の製造方法に関するものである。 The present invention relates to a method for producing trifluoromethylarenes useful in the field of medicine / agrochemicals or electronic materials such as liquid crystals.
従来、アレーン類にトリフルオロメチル基(CF3基)を導入する手法としては、メチル基の変換、即ち、メチル基を一旦、塩素化によりCCl3基とした後、フッ化水素によりCF3基に誘導する手法が知られている(非特許文献1)。しかしながら、この手法は、2つの工程を経て合成される上、取扱いが難しく、極めて危険な化合物であるフッ化水素を用いるという点において、安全で効率の良い合成法ではない。
また、ハロゲン化アレーンからトリフルオロメチルトリメチルシラン(ルパート試薬)等のCF3化剤により、直接CF3基を導入する手法が知られている(非特許文献2)。しかしながら、この手法は、当量以上のヨウ化銅を用いることから、後処理の煩雑さ及び多量の金属含有廃棄物を出す問題点を有し、工業的な製造法としては満足できるものではない。
一方、この問題点を解決する手法として、触媒量のヨウ化銅を用い、ハロゲン化アレーンから、ルパート試薬によりCF3基を導入する手法が知られている(非特許文献3)。しかしながら、この文献では、強力な電子吸引性基であるニトロ基を持つヨウ化アレーンを基質として使用している(アレーンは一般にニトロ基等の強力な電子吸引性基が存在すると、上記の様な求核的な反応が起こり易くなる性質を有している)。そのため、同手法をそのまま広範な基質に適用できるものではなく、やはりCF3基の導入手法としては決して満足できるものではない。
Conventionally, as a method for introducing a trifluoromethyl group (CF 3 group) into arenes, conversion of a methyl group, that is, a methyl group is temporarily converted into a CCl 3 group by chlorination, and then a CF 3 group by hydrogen fluoride is used. There is known a technique for guiding to the above (Non-Patent Document 1). However, this method is not a safe and efficient synthesis method in that it is synthesized through two steps and is difficult to handle and uses hydrogen fluoride, which is a very dangerous compound.
Further, a method is known in which a CF 3 group is directly introduced from a halogenated arene by a CF 3 agent such as trifluoromethyltrimethylsilane (Rupert reagent) (Non-patent Document 2). However, since this method uses copper iodide in an equivalent amount or more, it has a problem of post-processing complexity and a large amount of metal-containing waste, which is not satisfactory as an industrial production method.
On the other hand, as a technique for solving this problem, a technique is known in which a catalytic amount of copper iodide is used and a CF 3 group is introduced from a halogenated arene by a Rupert reagent (Non-patent Document 3). However, in this document, an iodinated arene having a nitro group which is a strong electron-withdrawing group is used as a substrate (in general, if a strong electron-withdrawing group such as a nitro group is present, Nucleophilic reaction is likely to occur).

本発明の反応では、反応試剤の添加方法が重要な要素となる。即ち、予め(1)ヨウ化アレーン、フッ化金属塩、銅化合物、窒素化合物、溶媒を反応器に仕込み、所定の温度まで加熱した後、上記一般式(2)で表されるトリフルオロメチルトリアルキルシランを反応系中へ分割添加、または連続的に添加し、反応させることで、反応収率が顕著に改善される。
ここで、(2)トリフルオロメチルトリアルキルシランを反応系中に分割添加する場合は、添加開始から添加終了までの間に、全添加量を5〜50回、好ましくは10〜20回に分割して添加する。なお、分割添加は、各回の添加量を同量にする必要はなく、適宜、変更することができる。
また、(2)トリフルオロメチルトリアルキルシランを反応系中に連続して添加する場合は、添加開始から添加終了までの間に、全添加量を連続的に添加してゆく。なお、連続添加は、添加中、添加量を均一に維持する必要はなく、添加中の添加量を、適宜、変更することができる。
また、添加開始から添加終了までの時間は、0.5時間〜24時間、好ましくは1〜6時間である。通常、添加終了と同時に反応は終了しているが、未反応原料が残存している場合でも1〜3時間程度の熟成時間を設定することで反応は終了する。
このように、(2)トリフルオロメチルトリアルキルシランを、反応系に分割して、あるいは、連続して添加することにより、反応収率が顕著に改善される。
なお、予め(1)ヨウ化アレーン、(2)トリフルオロメチルトリアルキルシラン、フッ化金属塩、銅化合物、窒素化合物、溶媒を反応器に一括して仕込んで、反応させると、反応収率が劣り、本発明の効果が得られない。
In the reaction of the present invention, the method of adding a reaction reagent is an important factor. That is, (1) an iodine iodide arene, a metal fluoride salt, a copper compound, a nitrogen compound, and a solvent are charged in a reactor in advance and heated to a predetermined temperature, and then the trifluoromethyl trimethyl represented by the general formula (2) is used. The reaction yield is remarkably improved by adding the alkylsilane in the reaction system in a divided manner or by continuously adding and reacting.
Here, when (2) trifluoromethyltrialkylsilane is added into the reaction system in a divided manner, the total addition amount is divided into 5 to 50 times, preferably 10 to 20 times, from the start of addition to the end of addition. And add. In addition, division addition does not need to make the addition amount of each time the same amount, and can be changed suitably.
When (2) trifluoromethyltrialkylsilane is continuously added to the reaction system, all addition amounts are continuously added from the start of addition to the end of addition. In addition, the continuous addition does not need to keep the addition amount uniform during the addition, and the addition amount during the addition can be appropriately changed.
The time from the start of addition to the end of addition is 0.5 to 24 hours, preferably 1 to 6 hours. Usually, the reaction is completed at the same time as the addition is completed, but even when unreacted raw materials remain, the reaction is completed by setting an aging time of about 1 to 3 hours.
Thus, the reaction yield is remarkably improved by adding (2) trifluoromethyltrialkylsilane to the reaction system in a divided manner or continuously.
If (1) arene iodide, (2) trifluoromethyltrialkylsilane, metal fluoride, copper compound, nitrogen compound, and solvent are charged in a reactor and reacted in advance, the reaction yield is increased. The effect of the present invention cannot be obtained.

さらに、本発明の方法における反応温度は、室温から溶媒の還流温度の範囲であり、具体的には、20〜150℃、好ましくは50〜140℃の範囲である。
反応終了後は、常法に従い反応液に水を加えて塩類を溶解処理した後、抽出溶媒を添加し、有機層を分離する。続いて、晶析または蒸留等により、目的とするトリフルオロメチルアレーン類を得る。
このようにして得られる本発明のトリフルオロメチルアレーン類は、上記一般式(3)で表され、1H NMR、13C NMR、質量分析、ガスクロマトグラフィー等によって、その構造を特定することができる。
Furthermore, the reaction temperature in the method of the present invention is in the range of room temperature to the reflux temperature of the solvent, specifically 20 to 150 ° C, preferably 50 to 140 ° C.
