Metal vapor synthesis (MVS) technique provides a valuable synthetic route to obtain supported Pd nanoparticles featuring strictly controlled dimension (< 5 nm). These systems proved highly efficient catalysts in Mizoroki-Heck alkenylations of aryl halides (I, Br) with acrylates, to give the corresponding trans-cinnammates in high yields under batch reaction conditions. Here we wish to report our recent results in continuous-flow Mizoroki-Heck alkenylations using MVS-derived Pd nanoparticles deposited on pyridine-based organic supports, both in the form of powder (PVPy) and as mesoporous organic monoliths

Abstract
Metal vapor synthesis (MVS) technique provides a valuable synthetic route to obtain supported Pd nanoparticles featuring strictly controlled dimension (< 5 nm). These systems proved highly efficient catalysts in Mizoroki-Heck alkenylations of aryl halides (I, Br) with acrylates, to give the corresponding trans-cinnammates in high yields under batch reaction conditions. Here we wish to report our recent results in continuous-flow Mizoroki-Heck alkenylations using MVS-derived Pd nanoparticles deposited on pyridine-based organic supports, both in the form of powder (PVPy) and as mesoporous organic monolithsFile in questo prodotto:
