The project is dedicated to the development of new synthetic systems for the efficient cleavage of phosphoesters. The goal of the project is to develop scientifically based approaches to the creation of functional materials based on metal complexes that would be highly effective catalysts for the cleavage of compounds with phosphoester bonds; development of methods for the synthesis of coordination metal compounds, with a main emphasis on mono- and polynuclear complexes based on chelate and binuclear pyrazolate ligands, study of the relationship between the features of their molecular structure, the nature of metal ions, physicochemical (spectral, magnetic, electrochemical) parameters and catalytic efficiency in phosphoester cleavage reactions and development on this basis of a strategy for creating a new generation of highly efficient catalysts for the hydrolytic cleavage of compounds with phosphoester bonds. The project involves searching for rational synthetic routes to obtain target coordination compounds that catalyze the cleavage of a wide range of phosphoesters, their characterization using a combination of various analytical and physicochemical methods. Ways of using new materials as effective catalysts for the cleavage and neutralization of organophosphorus pesticides and toxic substances will be identified.  Product Description popup.authors Bibik Yurii S.
