| Abstract: | The synthesis and characterization of a stable 1,2-bis(ferrocenyl)diphosphene, wherein a Pdouble bond, length as m-dash]P π-bond connects two ferrocenyl units will be reported. This represents an unprecedented example for a d-π electron system containing a heavier pnictogen π-spacer group. Stabilization of the highly reactive Pdouble bond, length as m-dash]P π-bond was achieved by steric protection using two bulky ferrocenyl moieties. |
