Abstract

Palladium has been supported on 2-((3-(piperazin-1-yl) propylimino)methyl)phenol functionalized magnetite nanoparticles (denoted as Fe3O4@SiO2@L-Pd(II)). The supported Pd was used as an active heterogeneous catalyst in Suzuki cross-coupling reaction under solvent-free conditions. This nanocatalyst could be facilely separated via magnetic concentration and the isolated catalyst exhibited long-term stability. Easy work-up, high yield, recycling of the catalyst, low reaction times, non-toxicity of catalyst and and solvent-free conditions as an environmentally benign procedure are the main merits of this protocol.The produced catalyst were characterized by XRD, FT-IR, XPS, SEM, TEM, EDAX, VSM, TGA and ICP-OES.
