文摘

Pd-CNT nanocomposite was prepared from the composite of thiolated MWNT and Na₂PdCl₄. The palladium nanoparticles possess an average diameter of 2.9?nm with a narrow size distribution for the Pd-CNT. This Pd-CNT showed good activities in the coupling reactions of aryl iodides and aryl alkynyl carboxylic acids to produce the diaryl alkynes in good yields without any additional ligand.
