Bis(pentamethylcyclopentadienyl)diphosphene-a Molecule with Fluxional Structure and Reactive PC Bond

What potential does the pentamethylcyclopentadienyl ligand Cp* have in diphosphene chemistry? An indication is provided by the synthesis of the crystalline diphosphene Cp*PPCp* from Cp*PCl2. The two Cp* ligands kinetically stabilize the PP bond, resulting in a fluxional structure (degenerate [1,...

Zusammenfassung:What potential does the pentamethylcyclopentadienyl ligand Cp* have in diphosphene chemistry? An indication is provided by the synthesis of the crystalline diphosphene Cp*PPCp* from Cp*PCl2. The two Cp* ligands kinetically stabilize the PP bond, resulting in a fluxional structure (degenerate [1,5]‐sigmatropic rearrangements). They may be successively replaced by bulky amino or alkyl ligands.
