Ferromagnetic α-Fe₂O₃ NPs: a potential catalyst in Sonogashira–Hagihara cross coupling and hetero-Diels–Alder reactions

Abstract

Applications of <italic>in situ</italic> generated ferromagnetic α-Fe₂O₃ NPs as an efficient and recyclable catalyst for carbon–carbon bond formation <italic>via</italic> Sonogashira–Hagihara coupling reactions and the synthesis of pyran derivatives by hetero-Diels–Alder reactions have been demonstrated.
