Divalent phosphenium ions [R 2 P] + are highly reactive, Lewis superacidic carbene analogues requiring electronic stabilization, which is usually provided by donor atoms. In A. H. Cowley's bis(ferrocenyl)phosphenium ion (a species lacking any obvious donors), significant Fe ⋅⋅⋅ P interactions were found to have a stabilizing effect on the [Fc 2 P] + ion. S. Mebs, J. Beckmann, and co‐workers came to this conclusion in their Communication on page 1581 in which they examined the molecular and electronic structure of this species.
