Research Abstract

New methods to increase the control of radical reactions and radical polymerization reactions have been developed through deep understanding of the reactivities of organoheteroatom compounds. We have mainly carried out 1) the elucidation of the reactivity difference of heteroatom species used as precursors of carbon centered radicals, and 2) the use of diheteroatom compounds, which possess heteroatom-heteroatom sigma bond, for the control of the reactions. Besides these results, we also developed a new condition for the highly controlled and efficient living radical polymerization, which is triggered by photo-irradiation, and the new synthetic route to structurally highly defined polymers through the selective transformation of living polymer ends.
