Description
Summary:A novel magnetic ferrocene‐labelled ionic liquid based on triazolium, [Fe3O4@SiO2@Triazol‐Fc][HCO3], has been synthesized and has been successfully introduced as a recyclable heterogeneous nanocatalyst. The catalytic activity of the novel magnetic nanoparticles was evaluated in the one‐pot three‐component synthesis of a wide variety of Betti bases. A simple, facile and highly efficient green method has been developed for the synthesis of kojic acid‐containing Betti base derivatives at room temperature. Additionally, this new protocol has notable advantages such as short reaction times, green reaction conditions, high yields and simple workup and purification steps. Also, the novel nanocatalyst could be easily recovered using an external magnetic field and reused for six consecutive reaction cycles without significant loss of activity. The newly synthesized nanocatalyst was characterized using Fourier transform infrared spectroscopy, X‐ray diffraction, energy‐dispersive X‐ray spectroscopy, field emission scanning electron microscopy, transmission electron microscopy and Brunauer–Emmett–Teller measurements. A novel [Fe3O4@SiO2@Triazol‐Fc][HCO3] nanocatalyst was synthesized, characterized and applied as an efficient heterogeneous catalyst for the synthesis of a wide variety of pyran‐containing Betti base derivatives at room temperature.
