Abstract

A catalytic membrane reactor, which was immobilized with palladium-loaded nanogel particles (NPs), was developed for continuous-flow Suzuki coupling reaction. Palladium-loaded membranes were prepared by immobilization of NPs, adsorption of palladium ions, and reduction into palladium(0). The presence of palladium in the membrane was confirmed by the scanning electron microscopy; palladium aggregation was not observed. The catalytic activity of the membrane reactor in continuous-flow Suzuki coupling reaction was approximately double that of a comparable reactor in which palladium ions were directly adsorbed onto an aminated membrane. This was attributed to the formation of small palladium particles. The reusability in the continuous-flow system was higher than that in a batch system, and the palladium-loaded membrane reactor had high long-term stability.
