Immobilization of NHC-bearing palladium catalysts on polyvinylpyridine; applications in Suzuki-Miyaura and Hartwig-Buchwald reactions under batch and continuous-flow conditions.

[摘要]：The facile coordinative immobilization of Organ's PEPPSI catalyst on a composite material composed of megaporous glass and polyvinylpyridine is described. The catalyst showed very good performance in Suzuki-Miyaura as well as Hartwig-Buchwald reactions of aryl chlorides under mild conditions and with low catalyst loadings. The modified PEPPSI catalyst was probed both under batch mode and continuous-flow applications. The flow setup was also utilized to shed light on the stability of the PEPPSI catalyst and the mobility of palladium.
