摘要
A novel magnetically heterogeneous nanocatalyst has been successfully synthesized via the immobilization of piperazine on tris (hydroxymethyl) aminomethane-coated Fe3O4 magnetic nanoparticles. The described catalyst was fully characterized by various techniques such as FT-IR, EDS, DTG/TGA, XRD, TEM, SEM, and VSM analyses. The catalytic efficacy of Fe3O4@THAM-piperazine has investigated for one-pot synthesis of tetrahydrobenzo[b]pyran and 1,8-dioxo-octahydro-xanthene derivatives. Notable features of this user-friendly catalytic system include high yields, high catalytic activity, simple operation, non-toxicity, and easy work-up. Also, the new nanocatalyst could be easily recovered and reused for six times without significant loss of activity. [GRAPHICS]
