Description
NaOH + Cl− → NaCl + OH−
NaOH + HCl → NaCl + H2O
NaClは、H2O以外の有機溶媒を使用する場合、目的物質との分離が難しく、OH−は、目的物質のTi−H結合に接近して、Ti−OH結合を形成する可能性があり、H2Oは、生成物のTi−H結合に接近し、これをTi酸化物(Ti oxide)に転換させる。
1)有機−遷移金属ハライドとアルミニウムハイドライド系列の化合物(metal aluminum hydride, MAH)を反応させて、有機−遷移金属−アルミニウムハイドライド複合体を製造する段階と、
2)前記有機−遷移金属−アルミニウムハイドライド複合体をルイス塩基(Lewis Base, LB)と反応させて、有機−遷移金属ハイドライドを製造する段階。

1)段階は、 有機−遷移金属−金属ハライドとアルミニウムハイドライド系列の化合物(MAH)を反応させて、有機−遷移金属−アルミニウムハイドライド複合体を製造する段階である。本段階で製造される有機−遷移金属−アルミニウムハイドライド複合体は、遷移金属とアルミニウムとの間に架橋水素結合(bridged hydrogen bond)が形成された化合物と認識される。本発明者らは、アルミニウムハイドライド化合物(MAH)の使用量によって、互いに異なる構造の有機−遷移金属−アルミニウムハイドライド複合体が形成され、次の段階であるルイス塩基との反応において、有機−遷移金属−アルミニウムハイドライド複合体構造によって、ハロゲン元素が完全に離脱されずに遷移金属末端に結合された反応副産物が生成される可能性があることを見出した。
2)段階は、有機−遷移金属−アルミニウムハイドライド複合体とルイス塩基(Lewis base;strong electron donor, LB)を反応させて、有機−遷移金属−ハイドライドを製造する段階である。
