報告名称 d-f遷移金属混合型錯体による新反応場の構築
報告概要 新しい触媒の開発は、医薬品や高分子などの現代社会の成立に不可欠な有機物質を効率よく合成する手法の飛躍的進歩に繋がるだけでなく、新規機能性材料の創出にも繋がりうるなど様々な分野へ波及効果を持つ重要な研究課題である。高性能な新規触媒を開発するためには、各種金属の特性を最大限に活用し、斬新な分子設計に基づく新反応場の構築が極めて重要である。これまでは特に周期表の4族以降に位置する遷移金属を活性中心とする有機金属錯体触媒が活発に研究されてきたが、3族に属する希土類金属の錯体を触媒として利用する研究は少数に留まっていた。本課題ではそれら従来の遷移金属錯体とは異なる性質を持つと期待される希土類金属錯体を用いる触媒反応場の構築、特に複数の金属核が協奏的に作用する新しい多核構造を持つ希土類錯体触媒や、希土類を性質の異なる他の遷移金属錯体と結び付けた錯体触媒(d-f遷移金属混合型錯体)の開発、さらに、それらの新しい触媒を用いた新しい物質変換反応の開発を目標とし、研究を進めてきた
