This study introduces novel transmetallation reactions of iron-based dicarbollide complexes, enabling controlled synthesis of complex polymetallic clusters. These findings open new pathways for creating advanced inorganic materials.
Area of Science:
- Organometallic Chemistry
- Inorganic Synthesis
- Materials Science
Background:
- Ferrocene and its analogues are stable building blocks but lack transmetallation chemistry.
- Existing metallacarboranes do not undergo Fe-center transmetallation.
Purpose of the Study:
- To prepare a charge-compensated Fe(bis)(dicarbollide) species.
- To investigate unprecedented transmetallation reactions of this species.
- To explore the reactivity of derived lithium-carbenoid species.
Main Methods:
- Preparation of a novel Fe(bis)(dicarbollide) complex.
- Transmetallation reactions with Iridium and Copper complexes.
- Deprotonation to form a lithium-carbenoid species.
Main Results:
- Achieved unprecedented transmetallation of the Fe-center to Iridium.
- Demonstrated controlled sequential transmetallation to form heterobimetallic and trimetallic clusters.
- Observed unique reactivity of the lithium-carbenoid moiety.
Conclusions:
- Developed new synthetic routes for polymetallic clusters.
- Established novel transmetallation pathways for Fe-dicarbollide systems.
- Showcased the potential of these complexes in constructing intricate inorganic architectures.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
