摘要：A magnetically separable core-shell-shell nanosphere, Fe3O4@nSiO(2)-SO3H@MS-NHCOCH3 (n = nonporous, MS = microporous SiO2), was fabricated as an acid-base collaborative catalyst for the three-component cyclization of aromatic aldehydes, nitroalkane, and sodium azide to afford 1H-1,2,3-triazoles. The bifunctional heterogeneous catalyst showed high activity for this transformation and good chemoselectivity, and toxic HN3 was not released during the course of the reaction. A variety of aldehydes were transformed into the corresponding 5-aryl-1H-1,2,3-triazoles in up to 98% yield. Furthermore, the catalyst could be recovered by using an external magnetic field and reused many times without any loss in activity. In contrast, a homogeneous catalyst system comprising ammonium acetate/acetic acid also worked in this three-component cyclization to afford 1H-1,2,3-triazoles.
