Description

本発明は、光触媒を用いて光により発生させたトリフルオロメチルラジカル及びニトリル類をオレフィン類に反応させトリフルオロメチル基含有アミノ化合物を製造する方法に関する。トリフルオロメチル基含有アミノ化合物は医農薬の合成中間体や電子材料の合成中間体として有用な化合物である。   The present invention relates to a method for producing a trifluoromethyl group-containing amino compound by reacting a trifluoromethyl radical and nitriles generated by light using a photocatalyst with olefins. A trifluoromethyl group-containing amino compound is a useful compound as a synthetic intermediate for medical and agricultural chemicals and a synthetic intermediate for electronic materials.

本発明の、光触媒を用いて光により発生させたトリフルオロメチルラジカル及びニトリル類をオレフィン類に反応させトリフルオロメチル基含有アミノ化合物を製造する方法は知られていない。   There is no known method for producing a trifluoromethyl group-containing amino compound by reacting a trifluoromethyl radical and nitriles generated by light using a photocatalyst with an olefin.

従来技術のトリフルオロメチルラジカルを用いる方法としては、S−(トリフルオロメチル)ジベンゾチオフェニウムテトラフルオロボラートや1−トリフルオロメチル−1,2−ベンズヨードオキソール−3−オンをトリフルオロメチルラジカル源として用い、銅触媒の存在下、オレフィン類にトリフルオロメチル基を導入する方法が知られている(非特許文献1,2,3)。   As a method using a trifluoromethyl radical of the prior art, S- (trifluoromethyl) dibenzothiophenium tetrafluoroborate or 1-trifluoromethyl-1,2-benziodooxol-3-one is used as trifluoro. A method of introducing a trifluoromethyl group into an olefin in the presence of a copper catalyst as a methyl radical source is known (Non-Patent Documents 1, 2, and 3).

また、光反応としては、トリス(2,2’−ビピリジン)ルテニウム ジクロリド錯体等を触媒として用い、ハロゲン化アルキル類にオレフィン類を挿入する方法(非特許文献4)、芳香族炭化水素類にトリフルオロメチル基を導入する方法(非特許文献5,6)、オレフィン類にトリフルオロメチル基と水酸基を導入する方法(非特許文献7)等が知られている。   In addition, as a photoreaction, tris (2,2′-bipyridine) ruthenium dichloride complex or the like is used as a catalyst, and an olefin is inserted into an alkyl halide (Non-patent Document 4). A method for introducing a fluoromethyl group (Non-Patent Documents 5 and 6), a method for introducing a trifluoromethyl group and a hydroxyl group into olefins (Non-Patent Document 7), and the like are known.

従来の非特許文献1〜7の方法については、オレフィン類への各種ラジカル付加反応によりラジカル付加物を得る方法であるが、同時にアミノ基を導入することはできなかった。   The conventional methods of Non-Patent Documents 1 to 7 are methods for obtaining radical adducts by various radical addition reactions to olefins, but it was impossible to introduce an amino group at the same time.

本発明者らは、光反応により発生させたトリフルオロメチルラジカルのオレフィン類への付加反応について、鋭意検討した結果、ニトリル類存在下、反応を実施することにより、トリフルオロメチルラジカルの付加と同時にアミノ基が導入できることを見出し、本発明を完成させるに至った。   As a result of intensive studies on the addition reaction of the trifluoromethyl radical generated by the photoreaction to the olefins, the present inventors conducted the reaction in the presence of nitriles, thereby simultaneously adding the trifluoromethyl radical. The inventors have found that an amino group can be introduced, and have completed the present invention.
