摘要：

Highly active recyclable Pd catalysts modified with a rigid C,N,C-tridentate pincer carbene ligand were successfully applied to the coupling of aryl halides with terminal acetylenes. The immobilization of Pd(11) complexes onto clays has beneficial effects on the recyclability of the catalytic activity over consecutive runs and also on the catalyst's stability, preventing it from Pd(0) formation.
