含有末端酰胺磷配体的磷枝状大分子是铑(I)催化[2 + 2 + 2]环加成反应的高效可回收催化剂。在活性和对映体辨别中观察到强烈的正枝状效应，导致轴手性联芳基化合物。
Phosphorus dendrimers containing terminal phosphoramidite ligands have been found to be highly effective and recoverable catalysts for the rhodium(I) catalyzed [2 + 2 + 2] cycloaddition reactions. A strong positive dendritic effect is observed both in the activity and enantiodiscrimination leading to axially chiral biaryl compounds.
