PdPtZn and PdZn nanoparticle (NP) thin films were synthesized by the reduction of [PdCl 2 (cod)], [PtCl 2 (cod)] (cod = cis,cis-1,5cyclooctadiene) and [Zn(acac) 2 ] (acac = acetylacetonate) complexes at an oil-water interface. The structure and morphology of the as-prepared NPs were characterized with X-ray diffraction, transmission electron microscopy and energy dispersive analysis of X-rays. Catalytic activity of the prepared NPs was investigated in the Suzuki-Miyaura cross-coupling reaction in H 2 O-EtOH and various micellar media systems such as cetyltrimethylammonium bromide (cationic surfactant), sodium dodecylsulfate (anionic surfactant) and Pluronic P123 (non-ionic surfactant). PdPtZn and PdZn thin films exhibited higher catalytic activity compared to Pd thin film in the Suzuki-Miyaura coupling reaction due to the appropriate interaction between palladium, platinum and zinc metals.

Slightly better yields are obtained using PdPtZn nanoparticles in a mixture of water and cetrimide. The applied catalytic system can be recycled at least four times. -(HOSEINI*, S. J.; ZAREI, A.; RAFATBAKHSH IRAN, H.; Appl. Organomet. Chem. 29 (2015) 8, 489-494, http://dx.
