Iron(III) decorated magnetic Fe3O4/chitosan-dithiocarbamate for aqueous oxidation of benzylic alcohols at room temperature

Heterogeneous catalysts play an important role in the field of organic transformations 1. On the other hand, since catalysts are one of the key components "green chemistry", the design and use of environmentally benign catalysts is one of the urgent challenges for chemists 2. Fe3O4 nanoparticles have been extensively studied because of structural and functional elements have various novel applications 3. In this work, Fe(III) were complexed by a modified Fe3O4-CSDTC composite as a stable catalyst Figure 1. Separable Fe3O4- CSDTC/Fe+3 demonstrated excellent performance with high yields for various benzylic alcohols in the presence of H2O2 at ambient temperature, so that Fe3O4-CSDTC was recovered and reused several times without significant decrease in activity.
