Cover Feature: Introduction of a Phosphine Group onto the Ferrocene Moiety in Ferrociphenol Opens Access to New Heterobimetallic Complexes with Anticancer Activity (ChemistryEurope 4/2025)

The Cover Feature shows a new ferrociphenol derivative that was designed to equip a prominent organometallic anticancer agent with an additional phosphine group capable of coordinating other metal centers. In their Research Article (DOI: 10.1002/ceur.202500048), B. Bertrand, J. Schulz and co-workers report the syntheses of this compound, its corresponding phosphonium salt, and transition metal complexes incorporating the functional phosphine, along with their preliminary evaluation as anticancer agents.
