栓系二炔与1-炔基硫化膦在铑催化下的反应提供了相应的具有大体积芳基的硫化膦。随后的双酰化反应产生了庞大的膦，它们将潜在地在过渡金属催化的反应中充当配体。
The reaction of tethered diynes with 1-alkynylphosphine sulfides under rhodium catalysis provides the corresponding phosphine sulfides having a bulky aryl group. The following desulfidation yields bulky phosphines that will potentially serve as ligands in transition-metal-catalyzed reactions.
