Hydrotalcite-supported Pd-Au nanocatalysts were found to be efficient heterogeneous catalysts for Ullmann homocoupling reactions of aryl bromides or chlorides at 25 or 40 °C, which could be due to the ensemble effect and increased electron density of Pd sites on Pd-Au nanoparticles, and the assistan...

Summary:Hydrotalcite-supported Pd-Au nanocatalysts were found to be efficient heterogeneous catalysts for Ullmann homocoupling reactions of aryl bromides or chlorides at 25 or 40 °C, which could be due to the ensemble effect and increased electron density of Pd sites on Pd-Au nanoparticles, and the assistant role of the hydrotalcite for the reversion of the catalytic active center, Pd(0). Ullmann homocoupling reactions of aryl bromides or chlorides at 40 °C were realized by using Pd-Au x nanocatalysts supported on Mg 3 -Al hydrotalcite.
