| Outline of Final Research Achievements |
Palladium-catalyzed cross-coupling reactions are activated by phosphines with high-donicity as well as steric bulk. This work purposed to apply hypervalent phosphorus compounds as an activator for transition metal-catalyzed cross coupling reactions. Phosphorus compounds with hypervalent electronic state are expected to be a highly steric demanding and electron donating ligand. In this work, a series of novel hypervalent phosphorus compounds was successfully synthesized utilizing a terphenyldiol-type tridentate ligand. In addition, quite rare species, i.e., stable dihydrophosphorane was isolated, which is expected to work as dihydrogen source for synthetic chemistry.
