Nano silicated-FeAl₂O₄ functionalized by DL-alaninium nitrate ionic liquid (FeAl₂O₄-SiO₂@[DL-Ala][NO₃]) as versatile promotor for aqua-mediated synthesis of spiro[chromenopyrazole-indene-triones and spiro[chromenopyrazole-indoline-diones.

ABSTRACT: In this work, the spinel FeAl₂O₄ was prepared and functionalized step-by-step with silica and alaninium nitrate ionic liquid ([DL-Ala][NO₃]) to produce a bio-based multi-layered nanostructure (nano FeAl₂O₄-SiO₂@[DL-Ala][NO₃]). The obtained magnetized inorganic-bioorganic nanohybrid characterized by Fourier transform infrared spectroscopy (FT-IR), vibrating-sample magnetometry (VSM), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDAX), transmission electron microscopy (TEM), thermogravimetric analysis/differential scanning calorimetry (TGA/DSC), X-ray fluorescence (XRF), and X-Ray diffraction (XRD) analysis. A facile synthesis of some tricyclic dihydro-spiro[chromeno[2,3
