Pyridinyl Functionalized MCM-48 Supported Highly Active Heterogeneous Palladium Catalyst for Crosscoupling Reactions
An MCM-48 supported 2-pyridinylmethanimine Pd-catalyst was found to be a highly efficient catalyst in the Mizoroki–Heck, Suzuki–Miyaura and copper-free Sonogashira cross-coupling reactions of aryl halides under aqueous reaction conditions. The catalyst efficiently promoted these coupling reactions...

| Summary: | An MCM-48 supported 2-pyridinylmethanimine Pd-catalyst was found to be a highly efficient catalyst in the
Mizoroki–Heck, Suzuki–Miyaura and copper-free Sonogashira cross-coupling reactions of aryl halides
under aqueous reaction conditions. The catalyst efficiently promoted these coupling reactions with ppm
levels of palladium to afford the corresponding coupling products in up to 98% yield. The supported Pdcatalyst
was readily recovered and reused several times without significant loss of its catalytic activity. |
