Abstract

A combined palladium-rhodium catalyst, generated by silica sol-gel-co-entrapment of metallic palladium and [Rh(cod) (μ-Cl)]2, catalyzes under ambient conditions the hydrogenation of toluene and other simple benzene derivatives. The catalyst is perfectly recyclable and promotes at 80°C and 400 psi, also the hydrogenation of polycyclic and sterically hindered arenes that are capable of penetrating the matrix pores. A synergistic effect is assumed to exist between the two metals, as either of the entrapped metallic components is a less active catalyst than the combination of both.
