Title : Catalytic potential of vanadium coordination compounds in oxidation reactions

Abstract:

In the context of global climate change, the diminishing availability of fossil fuels, and prevailing geopolitical tensions, Europe is actively seeking energy-efficient and resource-conservative strategies. This approach is being implemented across various sectors, including academia, with a particular focus on reducing reliance on organic solvents predominantly sourced from non-renewable fossil fuels. The imperative now is to develop methods for the synthesis of both inorganic and organic compounds that eschew the use of solvents entirely. Molybdenum-based catalysts have gained recognition for their efficacy and selectivity in various oxidation reactions, including epoxidations. Building on this foundation, the research has expanded to explore vanadium coordination compounds as potential catalysts for oxidizing alcohols. Terpenic alcohols, for instance, have garnered interest as precursors for the manufacture of fine chemicals, fragrances, perfumes, and agrochemicals. Recent investigations have delved into the catalytic capabilities of both molybdenum and vanadium compounds in the oxidation of linalool, utilizing environmentally benign oxidants like tert-butyl hydroperoxide and minimizing catalyst use. These practices align with the principles of green chemistry, which advocates for the minimization of hazardous substance use and aims to reduce waste and energy consumption in chemical manufacturing processes. This body of research underscores a commitment to advancing sustainable and innovative solutions within the field of chemistry. It emphasizes the critical role of green chemistry in adopting environmentally friendly practices and leveraging renewable resources to satisfy the demands of diverse industries.

• Is this research that other faculty could use to expand their research or teaching? Yes, the research presented follows the principles of green chemistry and provides catalytic systems with good activity and selectivity parameters.

Biography:

J. Pisk got a Ph.D. in Chemistry in 2012. In 2010 she spent one year at LCC Toulouse and IUT P. Sabatier Toulouse III, France, where she learned the basics of catalysis. She was Marie Curie Cofund's fellow and did postdoctoral research at the LCC, Toulouse (Project “Diligent search for chemical bio-sources: Solvent-free homogeneous and heterogeneous oxidation processes catalyzed by polyoxometalates”). She was an Assistant Professor at the Faculty of Science, Zagreb, in 2018, and from 2023 she is an Associate Professor. Her major interest is the coordination chemistry of molybdenum and vanadium and the investigation of catalytic properties of the obtained materials.
