で示される構造を含む化合物(A2)からなる群より選択された少なくとも1種の触媒と、ハロゲン原子含有有機酸からなる共触媒の存在下、溶媒中[但し、前記触媒として芳香族化合物(A1)のみを用いる場合は、炭化水素系溶媒、エーテル系溶媒、ハロゲン化炭化水素系溶媒及びケトン系溶媒からなる群より選択された少なくとも1種の溶媒中]、オキシム化合物を転位させ、対応するアミド又はラクタムを生成させるアミド又はラクタムの製造法を提供する。
芳香族化合物(A1)において、芳香環には芳香族炭化水素環、芳香族複素環が含まれる。芳香族炭化水素環として、例えば、ベンゼン環等の単環式芳香族炭化水素環;ナフタレン環、アントラセン環、フルオレン環、フェナントレン環等の縮合環、ビフェニル環、テルフェニル環などの多環式芳香族炭化水素環が挙げられる。芳香族複素環として、例えば、ピロール環、フラン環、チオフェン環、イミダゾール環、ピラゾール環、トリアゾール環、テトラゾール環、オキサゾール環、イソオキサゾール環、チアゾール環等の5員の芳香族複素環;ピリジン環、ピラジン環、ピリミジン環、ピリダジン環、トリアジン環等の6員の芳香族複素環;インドール環、ベンゾイミダゾール環、ベンゾトリアゾール環、キノリン環、ビピリジル環、フェナントロリン環等の縮合複素環が挙げられる。芳香族炭化水素環としては、特にベンゼン環が好ましい。また、芳香族複素環としては、特にピリジン環、トリアジン環などの含窒素複素環が好ましい。
式(1)中、GはP、N、S、B又はSi原子を示し、LAは脱離基を示す。LAにおける脱離基としては、一般的な脱離性の官能基(特に、LA-Hとして脱離可能な基)であればよく、例えば、ハロゲン原子(フッ素原子、塩素原子、臭素原子、ヨウ素原子)、-OR′基(R′は有機基を示す)、カルボキシル基、アミノ基、スルホニルオキシ基等が例示される。これらの中でもハロゲン原子を好ましく使用できる。R′で表される有機基としては特に制限されないが、例えば、前記式(4a)で表されるアルキリデンアミノ基や前記式(5a)で表されるシクロアルキリデンアミノ基(特に、原料として用いられるオキシム化合物に対応するアルキリデンアミノ基やシクロアルキリデンアミノ基)、アルキル基、又はハロアルキル基などを好ましく使用できる。
本発明の製造法では、共触媒としてハロゲン原子含有有機酸を用いる。ハロゲン原子含有有機酸を共触媒として用いると、反応溶媒として非極性溶媒や低極性溶媒を用いても、反応が円滑に進行する。そのため、反応終了後、水を用いた抽出操作により、反応生成物と触媒とを簡易に分離することが可能となる。
オキシム化合物の転位反応は溶媒の存在下で行われる。溶媒としては、反応条件下で不活性なものであればよく(但し、前記触媒、共触媒に該当するものは除く)、例えば、酢酸、プロピオン酸などのアルカン酸;アセトニトリル、プロピオニトリル、ベンゾニトリルなどのニトリル;ホルムアミド、アセトアミド、ジメチルホルムアミド(DMF)、ジメチルアセトアミドなどのアミド;ニトロベンゼン、ニトロメタン、ニトロエタンなどのニトロ化合物;酢酸エチル、酢酸ブチルなどのエステル;ヘキサフルオロイソプロピルアルコール、トリフルオロエタノール等のフッ素系アルコール(後述);ペンタン、ヘキサン、ヘプタン、オクタン、デカン、ドデカン等の脂肪族炭化水素、シクロペンタン、シクロヘキサン、シクロオクタン、シクロデカン、シクロドデカン、シクロペンタデカン等の脂環式炭化水素、ベンゼン、トルエン、キシレン、エチルベンゼン、メシチレン等の芳香族炭化水素などの炭化水素(炭化水素系溶媒);ジプロピルエーテル、ジイソプロピルエーテル、ジブチルエーテル、ジヘキシルエーテル等の鎖状エーテル、テトラヒドロフラン、ジオキサン等の環状エーテルなどのエーテル(エーテル系溶媒);塩化メチレン、ジクロロエタン、クロロホルム、四塩化炭素、クロロベンゼン、トリフルオロメチルベンゼン等のハロゲン化炭化水素(ハロゲン化炭化水素系溶媒);アセトン、メチルエチルケトン、ジエチルケトン、ジイソブチルケトン、シクロヘキサノンなどのケトン(ケトン系溶媒)などが挙げられる。これらの溶媒は単独で用いてもよく、2種以上を混合して用いてもよい。なお、触媒として芳香族化合物(A1)のみを用いる場合は、炭化水素系溶媒、エーテル系溶媒、ハロゲン化炭化水素系溶媒及びケトン系溶媒(特に、炭化水素系溶媒、エーテル系溶媒及びケトン系溶媒)からなる群より選択された少なくとも1種の溶媒を用いる。
本発明において原料として使用するオキシム化合物は特に制限されず、製造しようとするアミド又はラクタムに応じて適宜選択することができる。例えば、下記式(4)又は式(5)で表される化合物が挙げられる。
オキシム化合物の転位反応において、反応温度は、使用するオキシム化合物の種類や、触媒、共触媒、溶媒等の種類により適宜選択でき、特に制限されない。例えば、0~250℃程度、好ましくは25~150℃程度、さらに好ましくは40~120℃程度である。反応は、窒素やアルゴンなどの不活性ガス雰囲気下で行ってもよく、空気雰囲気下又は酸素雰囲気下で行うことも可能である。本発明において、特に、空気雰囲気下、還流条件で好ましく反応を行うことができる。
オキシム化合物は、例えば以下に示す製造方法により製造すれば、温和な条件下で簡易かつ効率よく製造することができる上に、オキシム化合物を合成する反応と、オキシム化合物の転位によりアミド又はラクタムを生成させる反応とを、途中オキシム化合物を分離精製する工程を特に必要とせず、一段階で行うことも可能であるため、極めて有利である。
