| Popis: | A novel magnetic ionic nanoparticle network (MINN) comprising ultrasmall iron oxide nanoparticles as seeds and an immobilized ionic liquid as the interfacing ionic linker was prepared using a simple coupled ligand exchange–sol–gel strategy. The material demonstrated a combination of interesting features such as network structure, high ionic density, pronounced ionic liquid content, excellent redispersibility, magnetic response, and high surface area, never observed simultaneously in the previous ionic nanoparticle networks. It was found that MINN is an effective support for the immobilization of Pd nanoparticles. The catalyst exhibits outstanding catalytic activity, stability, reproducible dispersibility, and durability in the Suzuki cross-coupling of highly challenging substrates such as heteroaryl halides, ortho-substituted aryl halides, as well as aryl chlorides. Also, the catalyst was efficiently recovered using a new magnetic separation/redispersion strategy and exhibited no noticeable loss of perfor... |
