Full TextAbstract
Herein we synthesized Cu(II) immobilized on Fe3O4@Agarose functionalized with ethanolamine phosphate-salicylaldehyde Schiff base (Fe3O4@Agarose/SAEPH2/Cu(II)) as a new and cost-effective nanomagnetic catalyst. The nanomagnetic catalyst was characterized by FT-IR, XRD, VSM, SEM-EDX, TEM, TGA and ICP techniques and it was found that the size of particles was about 9-25 nm with spherical in shape and entrapment of the Fe3O4 particles in the hollow pore structure of agarose. The prepared nanomagnetic catalyst was showed excellent activity for preparation of 2-substituted imidazolines, oxazolines and thiazolines. The catalyst is easy to prepare and exhibits higher catalytic activity than some commercially available copper sources. More importantly, this nanomagnetic catalyst can be easily recovered by using a permanent magnet and reused for at least seven cycles without significant deactivation.
