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. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Recommanded Product: 21867-64-1).
1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Recommanded Product: 21867-64-1
