| Outline of Final Research Achievements |
In this study, research on catalytic transformations involving multiple bond cleavages and formations was conducted, and more than ten reactions were developed. Spirobiindanones, arylideneindanes, and dihydrophenanthrenes were synthesized by rhodium-catalyzed arylation. Ring-opening coupling reactions of cyclopropenones afforded alkenyl alkynyl ketones and spirocyclic cyclopentanones. Hydrazine derivatives underwent rhodium-catalyzed cyclization reactions to give indoles and phthalazinones. Maleic anhydrides coupled with alkynes and diynes to afford pyrones and benzenes, respectively. Rhodium-catalyzed reaction of pyridylmethylenecyclobutanes gave indanes through a skeletal rearrangement. On the other hand, pyridylmethylenecyclobutenes underwent rhodium-catalyzed intermolecular coupling with alkynes to afford multisubstituted benzenes.
