| Outline of Final Research Achievements |
Considering the economic and environmental problems of transition metals (rare resources, toxicity, difficulty in separation and recovery, handling, etc.), which are widely used in current organic synthesis, the development of organic synthesis methods using inexpensive and low-toxic iodine, which is abundant in Japan, has been promoted in recent years. In this study, new hypervalent iodine species and their catalytic generation methods were developed for the metal-free and efficient synthesis of heterocyclic compounds found in useful materials, and applied to heterocyclic synthesis with the introduction of carbon functional groups.
