摘要
Palladium nanoparticles on the polyaniline (Pd@PANI) catalyst are now easily prepared on a gram scale through the oxidative polymerization of aniline in the presence of PdCl2 by using air as a clean oxidant. The material is found to be very stable and can be stored for more than one year without deactivation. Thus, it may become a commercial reagent in organic synthesis, depending on its application scopes. This article reported the first example of Pd@PANI-catalyzed Sonogashira couplings free of copper and ligands.
