Metal-bio functionalized bismuthmagnetite [Fe_3−xBi_xO₄/SiO₂@l-ArgEt₃⁺I⁻/Zn(ii)]: a novel bionanocomposite for the synthesis of 1,2,4,5-tetrahydro-2,4-dioxobenzo[b][1,4]diazepine malononitriles and malonamides at room temperature and under sonication

Abstract

In this work, a new magnetized composite of bismuth (Fe3−xBixO4) was prepared and functionalized stepwise with silica, triethylargininium iodide ionic liquid, and Zn(ii) to prepare a multi-layered core–shell bio-nanostructure, [Fe3−xBixO4/SiO2@l-ArgEt3+I−/Zn(ii)].
