Outline of Final Research Achievements

New protocols for mild, efficient, and selective generations and synthetic transformations of silyl and germyl radicals are established by developing novel photo-excited electron transfer reactions. Furthermore, the first protocol of cis-thioboration of alkynes is also established based on new generation pathway for B and S radicals. These results provide new possibility for design and syntheses of hetero-element-containing functional molecules.

Academic Significance and Societal Importance of the Research Achievements

ケイ素やゲルマニウム等は、光・電子材料や医薬品をはじめとする様々な機能性分子の基本骨格として大きな期待が寄せられているため、効率的な14 族ヘテロ元素の導入・変換手法が強く求められている。本研究は、基底状態での反応化学に基づいた従来法からの脱却を目指し、電子励起・電子移動の活用による 14 族ヘテロ元素ラジカル種の新規発生法・変換法を実現し、ヘテロ元素を用いる分子変換・物質創製の新たな可能性を示してきた。更に、本研究により開発された14 族元素化学新反応は、温和な条件下で幅広い基質に適用でき、機能性材料や医薬品分子の創出への応用が期待される
