An efficient heterogeneous Pd catalytic system has been developed, based on immobilization of Pd nanoparticles (PNPs) on a silica-bonded N-propylpiperazine (SBNPP) substrate. The SBNPP substrate effectively stabilizes the PNPs and improves their stability against aggregation. The catalytic activity of this catalyst was investigated in the cyanation of aryl halides with K4[Fe(CN)6] as the cyanide source. The catalyst could be recycled several times without appreciable loss of catalytic activity.
Graphical abstractA simple and efficient procedure for the cyanation of aryl halides with K4[Fe(CN)6] in the presence of Pd nanoparticles on silica-bonded N-propylpiperazine (PNP-SBNPP) is described. This heterogeneous catalyst could be recycled several times without appreciable loss of catalytic activity.Figure optionsDownload full-size imageDownload as PowerPoint slide
