Abstract: Recebido em 5/3/10; aceito em 4/8/10; publicado na web em 16/11/10 Two complexes of Rh(I) and Pd(II) with chloride and tridecylamine ligands were obtained and characterized by Elementary Analysis and by XPS and FTIR spectroscopies. Complexes anchored on g-Al 2 O 3 were tested in the styrene semi-hydrogenation reaction carried out in the absence or presence of a sulfur poison. Although both low loaded catalysts were highly selective, the Pd(II) complex was three times more active than the Rh(I) complex. The rho… Show more

“…Such a reaction could be due to the interaction of Pd 0 with neighbouring pyrrolic cations. 66,70 The covalently bonded Pd 2+ could be stable, preventing further reduction of Pd 2+ to Pd 0 during synthesis.…”

“…59 The shi of the C-N peak to lower wavenumbers in the presence of Pd NPs is indicative of interactions between pyrrolic nitrogen and Pd NPs. 70,71 The interaction between Pd NPs and the surface of different supports was also studied by using TPR and the proles obtained are presented in Fig. 9B.…”
