Pd–Cu–Exchanged montmorillonite K10 clay: an efficient and reusable heterogeneous catalyst for vinylation of aryl halides

Palladium and copper exchanged montmorillonite K10 clay has been found to catalyse very efficiently the reaction between aryl halides (X = Br, I) and acrylates, and styrenes affording alkyl (E)-cinnamates and (E)-stilbenes respectively in high yields.
