摘要：

(Figure Presented) Quick recovery: The first magnetic-nanoparticle- supported organocatalyst is prepared. The heterogeneous catalyst promotes a range of nucleophilic reactions and can be recovered by exposure to an external magnet (see picture). Furthermore, it can be recycled over 30 times without loss of activity. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
