摘要：
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 degrees 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. (C) 2013 Elsevier B.V. All rights reserved.
