Cyclic Metallophosphines via an Unexpected Series of Metal-Mediated P–C and C–C Bond Rearrangements

Type: article

Abstract: (μ-dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) and internal alkynes (RC≡CR, R = Ph, Et) afford 52-electron trinuclear clusters which are best considered as comprising an 18-electron cyclic metallophosphine ligand coordinated to a diruthenium center. They result from an unexpected and unprecedented series of metal-mediated ligand transformations, including the double P-Ph cleavage of one end of the diphosphine and capture of each of the resulting phosphinidine and benzyne ligands by the alkyne.
