The Bis(ferrocenyl)phosphenium Ion Revisited

The bis(ferrocenyl)phosphenium ion, [Fc(2)P](+), reported by Cowley et al. (J. Am. Chem. Soc. 1981, 103, 714–715), was the only claimed donor‐free divalent phosphenium ion. Our examination of the molecular and electronic structure reveals that [Fc(2)P](+) possesses significant intramolecular Fe⋅⋅⋅P...

description The bis(ferrocenyl)phosphenium ion, [Fc(2)P](+), reported by Cowley et al. (J. Am. Chem. Soc. 1981, 103, 714–715), was the only claimed donor‐free divalent phosphenium ion. Our examination of the molecular and electronic structure reveals that [Fc(2)P](+) possesses significant intramolecular Fe⋅⋅⋅P contacts, which are predominantly electrostatic and moderate the Lewis acidity. Nonetheless, [Fc(2)P](+) undergoes complex formation with the Lewis bases PPh(3) and IPr to give the donor–acceptor complexes [Fc(2)P(PPh(3))](+) and [Fc(2)P(IPr)](+) (IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazole‐2‐ylidene).
