Researchers from the Department of Chemistry, Dino Kuzman, Josipa Sarjanović, Mirna Mandarić, Marina Cindrić, Jana Pisk and Višnja Vrdoljak, in collaboration with Dominique Agustin from the University of Toulouse, have published a paper titled “Tailored pincer ligand-based oxidovanadium complexes of varying nuclearity and geometry: Catalytic performances and computational insights” in the Elsevier journal Inorganic Chemistry Communications (IF 5.4).
Hydrazone-based pincer ligands were used to prepare a series of oxidovanadium(V/IV) complexes with diverse nuclearities and geometries, including the metallosupramolecular polymers. The complexes catalyze selective oxidation of benzyl alcohols with t-butyl peroxide, where nuclearity influences conversion and suppression of overoxidation. DFT calculations provide mechanistic insights, supporting a stepwise pathway involving alkoxy exchange, substrate coordination, and hydrogen abstraction.
The research was funded by the Croatian Science Foundation as part of the research project Supramolecular and hybrid metal-organic coordination assemblies – cooperative effects and activity/property prediction (MOCASS IP-2022-10-7368)
