Terphenyl(bisamino)phosphines have been identified as effective ligands in cationic gold(i) complexes for the hydroamination of acetylenes. These systems are related to Buchwald phosphines and their steric properties have been evaluated. Effective hydroamination was noted even at low catalyst loadings and a series of cationic gold(i) complexes has been structurally characterized clearly indicating stabilizing effects through gold-arene interactions.
三联苯（双氨基）膦已被确定为阳离子金（I）配合物中用于乙炔氢胺化反应的有效配体。这些体系与布赫瓦尔德膦有关，并且已经评估了它们的空间性质。即使在低催化剂负载量下也能观察到有效的氢胺化反应，并且一系列阳离子金（I）配合物已通过结构表征，清楚地表明了通过金-芳烃相互作用产生的稳定作用。
