Copper- and Palladium-Containing Perovskites: Catalysts for the Ullmann and Sonogashira Reactions

The utility of perovskite-based materials in organic synthesis is explored through examination of a series of copper- and palladium-containing perovskites in Ullmann and Sonogashira type reactions. La0.9Ce0.1Co0.6Cu0.4O3 is identified as an effective catalyst for the synthesis of a range of biaryl ether and thioether functionalities, whilst a Cu- and Pdcontaining perovskite is effective in the Sonogashira reaction. These results suggest that perovskites may be useful leads in the search for new catalysts and reagents for organic synthesis.
