Carbon-Free Ferrocene: A New Era for Transition-Metal Chemistry and Catalysis

Chemists are developing a carbon-free successor to ferrocene, a foundational molecule in organometallic chemistry. By removing the traditional carbon scaffolding while maintaining stability and symmetry, researchers aim to create new catalysts and materials for industrial use. This shift could reduce reliance on carbon-based ligands and open new pathways in materials science and biomedicine. The goal is to find a modular building block that offers the same tunability and predictability as the original molecular sandwich.
