| Research Abstract |
Rhenium is not a popular element in organic synthesis. Through this research, we tried to clarify the features of the metal, especially unknown and useful reactivities for organic synthesis. We have found the following synthetic reactions by using rhenium complexes as probes. (1) Lewis-acid catalyzed reactions with rhenium complexes. (2) Reactions based on the C(sp2)-H bond activation with rhenium complexes. (3) Reactions based on the C-C bond cleavage between carbonyl and -carbons with rhenium complexes. (4) Formation of heteroatom-carbon bonds by activation of heteroatom-hydrogen and C-H bonds at proximity positions. (5) Novel C-C bond cleavage reactions catalyzed by other transition metals than rhenium.
