负载在HY沸石上的Rh（C2 H4）2络合物在H2存在下选择性地催化乙烯二聚，但是锚定在铑附近的铱络合物通过溢出氢而改变选择性，这限制了乙烯在与铑位点协同作用的Al-OH位点上的吸附，从而触发铑络合物作为氢化而不是二聚催化剂操作。
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.
