| Outline of Final Research Achievements |
Pheox-Al complexes with various phosphino groups were successfully synthesized. Specifically, complexes with diphenylphosphino or dicyclohexylphosphino groups were synthesized. The Lewis basic properties of these complexes can be changed by substituents on the phosphino group, and these complexes formed adducts with various compounds. These aluminum complexes were found to be catalytically active in the cycloaddition reaction of epoxides with isocyanates.

本研究ではアルミニウムの新奇特性を発見することができた。したがって、その新奇特性を利用した物性発現、反応開発や材料開発が連鎖的に増大していき、一つの分野を形成できるために学術的なインパクトは大きい。また、確立する触媒設計のコンセプトはアルミニウム以外の典型金属にも適用することができる。有機工業化学において、遷移金属を豊富で安価な典型金属によって置き換えていくこともできるために工業界にも貢献できる。
