▎ 摘　　要

Indoles and benzofurans have been synthesized using a graphene oxide-grafted aminobisphosphine-Pd-II complex (GO@PNP-Pd) under copper-free condition. A range of indole and benzofuran derivatives have been made by the reaction of N-protected 2-iodoanilines and 2-iodophenols with terminal acetylenes in presence of GO@PNP-Pd. The activity of the aminobisphosphine-Pd-II complex remains the same under both homogeneous and heterogeneous conditions. Finally, the recycling ability of the immobilized catalyst (GO@PNP-Pd) has been examined for five consecutive runs with appreciable conversion.
