Abstract
A novel clay catalyst containing a heterogenized Rh(I) triphenylphosphine c omplex (Rh-bentonite) has been prepared via ion exchange of a Hungarian Na-bentonite with Wilkinson complex [RhCl(PPh3)(3)]. It was established that the active species [Rh(PPh3)](+) was situated on the external surface of th e catalyst, which was found to be efficient in the liquid-phase hydrogenati on of 1-octene, cyclohexene, norbornadiene, 1,5-cyclooctadiene, phenylacety lene and cyclohexene-3-one.
