Synthesis of Indoles and Benzofurans Using a Graphene Oxide-Grafted Aminobisphosphine-Pd^II Complex.

ABSTRACT: 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.
