Research Abstract

The present study revealed that hexaphenylcarbodiphosphorane (CDP) can serve as a mono-, di-, or tri-dentate carbon (0) ligand for a variety of transition-metal complexes. Detailed studies demonstrated that the coordination modes of CDP can be controlled by the appropriate choice of the ancillary ligands on the metal center. A novel CDP bearing a chiral scaffold was also synthesized, and its transition-metal complexes were successfully isolated. In addition, unprecedented transformations proceeding via P-C bond cleavage were observed in several CDP complexes, indicating that CDP can be a valuable C1 source in synthetic organometallic chemistry.
