Abstract

Rh(C2H4)2 complexes supported on HY zeolite selectively catalyze ethylene dimerization in the presence of H2, but iridium complexes anchored near the rhodium alter the selectivity by spilling over hydrogen that limits the adsorption of ethylene on Al–OH sites that act in concert with the rhodium sites, thereby triggering the rhodium complexes to operate as hydrogenation rather than dimerization catalysts.
