Organic electro-synthesis could use electricity as the power for organic oxidation and reduction, which has great potentials for green chemical industry. The traditional organic electro-synthesis focuses on searching for electro-intermediates and reagents search. However, only few works are exploring the effects of the electrode. Here, for the first time, we apply nanomaterials as the catalysts for electrochemical C-C cross coupling. To be specific, our as-synthesized 2.5 nm CuPd nanoparticles could cross connect one inactivated halide (allylic halides) and one activated halide (allyl halides) with over 90% yield in water/isopropanol condition. Compared with traditional halide coupling which needs large amount of Pd salt and toxic electrolyte, our CuPd NP catalyst is more economical, efficient and environment friendly. Additionally, we investigate the mechanism of C-C cross coupling with Pd ions as the control and the results show that the nucleation of Pd ions to form Pd clusters is the key step of C-C coupling.<br/>
