| Outline of Final Research Achievements |
Developments of new catalytic reactions using rhodium-quinolinolato complexes as catalysts have been investigated. We have developed the [Rh(Q)(cod)]-catalyzed 2:1 coupling reaction of terminal alkyne and active methylene compounds leading to cyclopentene derivatives. We found that the coupling of aliphatic alkynes with alkyl acrylates gave cyclobutene derivatives in regioselective manner in high yields. In addition, we synthesized PNO tridentate ligands bearing diphenylphosphinomethylene group at 2-position of the quinolinolate moiety and prepared new types of rhodium complexes having this PNO tridentate ligand.
