Title
Palladium nanoparticles immobilized on magnetic nanoparticles: An efficient semi-heterogeneous catalyst for carbonylation of aryl bromides
Abstract

•A catalytic system was obtained by supporting Pd nanoparticles on Fe3O4 nanoparticles.•It catalyzed efficiently carbonylation reactions of aryl bromides.•The catalyst can be simply recovered by magnetic separation.•The catalyst could be reused five times without significant loss of activity.

We describe a method for supporting palladium nanoparticles on magnetic nanoparticles modified with amino-functionalized dihydro-imidazolium groups. This catalytic system is very efficient in alkoxy- and amino-carbonylation reactions of aryl bromides. The catalyst can be easily recovered from the reaction mixture by applying an external magnetic field and reused for over five consecutive cycles without a significant decrease in its activity.
