摘要：

The best of both worlds: The benefits of homogeneous and heterogeneous nanocatalysis are combined, whereby highly reactive colloidal Fe 3O 4 nanocrystals are generated in situ that remain in solution long enough to allow the efficient and selective reduction of nitroarenes to anilines in continuous-flow mode (see scheme). After completion of the reaction, the nanoparticles aggregate and can be recovered by a magnet. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
