Abstract:

This study reported a new application of CuFe₂O₄ spinel as an efficient heterogeneous catalyst for the selective oxidation of isoeugenol to licarin A under mild conditions. The CuFe₂O₄ was prepared via a simple method and characterized by various modern techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDX), and high-resolution transmission electron microscopy (HR-TEM). The XRD and HR-TEM results confirmed the structure and morphology of spinel materials, while the SEM–EDX provided valuable information on the material component. CuFe₂O₄ catalyst showed excellent catalytic activity in the selective oxidation of isoeugenol to give a high yield of licarin A under mild conditions. In addition, the catalyst was stable and able to reuse at least four times without the loss of catalytic activity.
