Palladium-catalyzed annulation of 1-alkynylphosphine sulfides with 2-iodoanilines followed by desulfidation affords 3-substituted 2-indolylphosphines. This annulation/desulfidation sequential protocol offers a conceptually new approach to bulky heteroarylphosphines.

We reported herein rhodium(III)-catalyzed C–H activation and annulation reactions for the synthesis of bulky phosphine ligands by using 1-alkynylphosphine sulfides as key starting materials. In the presence of [Cp*RhCl2]2 (5 mol %) and CsOAc (2.0 equiv), various N-(pivaloyloxy)benzamides (3.0 equiv) could react smoothly with 1-alkynylphosphine sulfides at 40 °C in MeOH/CF3CH2OH cosolvent without external

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.
