Title
Pd nanoparticles immobilized in [bmim][PF6] supported on laponite clay as highly recyclable catalysts for the Mizoroki–Heck reaction
Abstract

•Straightforward preparation of supported palladium nanoparticles.•Thin films of ionic liquid on laponite synthetic clay as support.•Easy manipulation of supported Pd nanoparticles thanks to support effects.•Mizoroki–Heck cross-coupling reactions in solventless conditions.•Easy reaction work-up and high recoverability of catalysts (up to 17 times).

Mizoroki–Heck cross-couplings of aryl halides catalyzed by highly active palladium nanoparticles, immobilized on [bmim][PF6] films supported on laponite clay, have been investigated. The reactions are performed at 100 °C in solventless conditions to afford the corresponding coupling products in good to excellent yields under non-anhydrous and non-degassed conditions. Highly recoverable catalytic systems have been prepared, allowing up to 17 catalytic cycles with good yields and excellent selectivities. A positive support effect seems to contribute to the long duration of these catalysts.
