Synthesis of bulky phosphines by rhodium-catalyzed formal [2+2+2] cycloaddition reactions of tethered diynes with 1-alkynylphosphine sulfides
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.
