Abstract

The synthesis and characterization of a stable 1,2-bis(ferrocenyl)diphosphene, wherein a P[double 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 P[double bond, length as m-dash]P π-bond was achieved by steric protection using two bulky ferrocenyl moieties.
