- Abstract
Abstract: Reduction of the FeII complex [(PhPP2Cy)FeCl2] (<bold>2</bold>) generated an electron‐rich and unsaturated Fe0 species, which was reacted with white phosphorus. The resulting new complex, [(PhPP2Cy)Fe(η4‐P4)] (<bold>3</bold>), is the first iron cyclo‐P4 complex and the only known stable end‐deck cyclo‐P4 complex outside Group V. Complex <bold>3</bold> features an FeII center, as shown by Mössbauer spectroscopy, associated to a P42− fragment. The distinct reactivity of complex <bold>3</bold> was rationalized by analysis of the molecular orbitals. Reaction of complex <bold>3</bold> with H+ afforded the unstable complex [(PhPP2Cy)Fe(η4‐P4)(H)]+ (<bold>4</bold>), whereas with CuCl and BCF, the complexes [(PhPP2Cy)Fe(η4:η1‐P4)(μ‐CuCl)]2 (<bold>5</bold>) and [(PhPP2Cy)Fe(η4:η1‐P4)B(C6F5)3] (<bold>6</bold>) were formed.
