Abstract The use of dendritic structures for the grafting of core–shell γ-Fe 2 O 3/polymer 300 nm superparamagnetic nanoparticles (MNPs) has been performed with four metallodendrons that were functionalized with diphosphinopalladium complexes. The catalytic performance of these nanocatalysts was optimized for the Suzuki C [BOND] C cross- coupling reaction. These results demonstrated the importance of optimizing the catalytic ...
