Copper ferrite nanoparticles catalyzed formation of β-Ketophosphonates via oxyphosphorylation of styrenes with H-phosphonates: A DFT study on UV–vis absorption spectra

Abstract Typical copper ferrite nanoparticles (CuFe2O4) were used as a catalyst for one-pot synthesis of β-ketophosphonates via the reaction of alkenes with H-phosphonates under conventional heating conditions. The catalyst was prepared by using the coprecipitation method and was analyzed by physiochemical techniques. By using this catalyst system, several types of useful and new β-ketophosphonate products were obtained in very good to excellent yields under optimized reaction conditions in a novel way. Furthermore, the catalyst is recyclable and reusable from the reaction.
