すなわち、従来の製造法では、まず、ホスフィンオキシド誘導体にホスゲンなどの塩素化剤を反応させてホスフィンジクロリド誘導体を調製し、生成したホスフィンジクロリド誘導体を精製、単離した後、これを還元反応することによりホスフィン誘導体を合成する必要があった。精製・単離操作が必要なのは、塩素化剤や副生する塩素化物を限度内に減少させることが必要なためであり、また従来の方法だと操作に長時間を要するとともに収率の低下をもたらすものであった。これに対し、本発明の製造法は、還元反応において、塩素化剤や副生する塩素化物の影響を受けないため、塩素化反応で生成した反応混合物から、ホスフィンジクロリド誘導体を精製、単離することなく、反応混合物をそのまま還元反応することができ、操作にかかる時間を短縮でき、収率を高めることができるものである。
また、ホスフィンジクロリド誘導体からホスフィン誘導体を合成する従来方法はいずれも90~180℃の高温反応条件で実施しており、処理時間も数時間~20時間の長時間かかるものが多かった。これに対し、本発明の方法では、従来の技術に比べ低温(例えば室温)で、かつ短時間(例えば10分間程度)で反応を行うことができる。更に、従来の方法では、アルミニウムは粉末状であらかじめ篩により適当な範囲の粒径(200~500μm)に揃えたものを使用する必要があった。しかし粒径の調整にコストがかかるだけでなく、粉末状のアルミニウムは発火しやすくその取り扱いには格別の注意が必要であった。これに対し、本発明の製造法によれば、アルミニウムの形状、粒径の制約が少なく、例えば、アルミニウム箔を使用することができ、取扱が極めて容易である。
このように、本発明の製造法によれば、アルミニウム及びイオン化傾向がアルミニウム以下の金属の塩を使用することにより、ホスフィンオキシド誘導体からの塩素化処理と還元反応を、危険性の高い薬品を使用することなく、従来技術に比べ低温かつ短時間で実施することができ工業的に有利に実施できる。更に、反応中間生成物(ホスフィンジクロリド誘導体)を精製、単離する必要がないため、高収率での製造が可能である。更に、全反応をワンポット(一つの反応容器)で実施することも可能であり、これにより工業的に極めて有利に実施することができる。
更に、本発明の製造法においては、1回目の反応を、過剰のアルミニウムを用いて行ない、固体として存在するアルミニウムを反応液からろ過等の方法で分離、回収し、回収したアルミニウムを用いて、更に2回目以降の反応を行うこともできる。このように、回収したアルミニウムを繰り返し用いて反応を行うことにより、2回目以降の反応を実施することができ、工業的に有利に実施することができる。
また、ホスフィンオキシド誘導体から簡単な前処理と電解還元をすることにより、ホスフィン誘導体を安価でかつ安全に工業的製造することができる。
次に、脂肪族炭化水素基(R)とはアルキル基、アルケニル基、アルキニル基等の脂肪族炭化水素基であり、置換基を有するものも含むものとする。
nは0~3の整数であり、n=3であるトリアリールホスフィンオキシド又はn=2であるジアリールアルキルホスフィンオキシドが好ましく用いられ、具体的には、トリフェニルホスフィンオキシド、トリ(p-トリル)ホスフィンオキシド、トリ(m-トリル)ホスフィンオキシド、トリ(o-トリル)ホスフィンオキシド、トリ(p-メトキシフェニル)ホスフィンオキシド、トリ(p-クロロフェニル)ホスフィンオキシド、トリ(2-フリル)ホスフィンオキシド、ジフェニルメチルホスフィンオキシド、ジフェニルエチルホスフィンオキシドが好ましく用いられ、トリフェニルホスフィンオキシドが最も好ましく用いられる。
このようにして還元反応で得られ反応混合物から、溶媒抽出、再結晶等の従来公知の方法によって分離、精製し、ホスフィン誘導体が得られる。反応混合物には、塩化アルミニウム、イオン化傾向がアルミニウム以下の金属塩が含まれており、これらを精製により除去する必要があり、精製後のホスフィン誘導体中の塩化アルミニウム含有量は10ppm以下とするのが好ましく、1ppm以下とするのが更に好ましい。また、イオン化傾向がアルミニウム以下の金属塩は1ppm以下とするのが好ましく、実質的に0ppmとするのが更に好ましい。
また、本発明において、上述のように、ホスフィンオキシド誘導体からホスフィン誘導体を製造するにおいて、過剰のアルミニウムを用いて反応を行ない(1回目の反応)、固体として存在するアルミニウムを反応液からろ過等の方法で分離、回収し、回収したアルミニウムを用いて、更に、ホスフィンオキシド誘導体からホスフィン誘導体を製造し、これを繰り返すことができる。(2回目以降の反応)。この場合、2回目以降の反応においては、イオン化傾向がアルミニウム以下の金属の塩を使用する必要がない。このように、2回目以降の反応でイオン化傾向がアルミニウム以下の金属の塩を添加せずに反応が進行することは、イオン傾向がアルミニウム以下の金属の塩により一度アルミニウムが活性化させると、繰り返し反応を行っても系中のアルミニウムは活性化された状態が続く事を示すものである。
なお、上記「過剰」とは、反応に用いられるアルミニウムの理論量(ホスフィンオキシド誘導体1モルに対してアルミニウム0.67モル)に対し、通常、2倍以上5000倍以下、好ましくは5倍以上500倍以下のアルミニウムを用いることをいう。
このように、回収したアルミニウムを用いて繰り返し反応を行うことにより、2回目以降の反応を効率よく実施することができ、工業的に有利に実施することができる。
