Dr. Marichev, Assistant Professor of Chemistry at GSU has just published a peer-reviewed paper in Inorganica Chim Acta!
This review examines literature up to 2023 on metal complexes with halogenated imidazol-2-ylidenes, focusing on structural diversity, key properties, and applications. The study highlights that halogen substitution at specific positions on the NHC ligands affects the metal complexes' electronic and steric properties, impacting their catalytic and medicinal uses. While most halogenated complexes are synthesized using standard methods, some require special procedures. The review notes that halogenated complexes often exhibit distinct advantages, such as enhanced crystallinity and stability, particularly with larger halogens like Br and I. However, challenges remain, including synthetic difficulties and a lack of standardized data, complicating direct comparisons with non-halogenated counterparts. The review emphasizes the potential for further research, particularly in exploring fluorinated complexes for their strong electron-withdrawing properties and potential biological activities.
