palladium supported on schiff base functionalized magnetite nanoparticles as an efficient catalyst for coupling reactions

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 the suzuki cross-coupling reaction under solvent-free conditions. this nanocatalyst could be facilely separated via magnetic concentration and the isolated catalyst exhibited longterm stability. easy work-up, high yield, recycling of the catalyst, low reaction times, non-toxicity of catalyst 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.
