Polystyrene resin-supported CuI-cryptand 22 complex: a highly efficient and reusable catalyst for the formation of aryl-sulfur bonds in aqueous media

摘要

The air and moisture stable polystyrene resin-supported copper(I) iodide-cryptand-22 complex (PS-C22-CuI) behaves as an efficient and robust heterogeneous catalyst in the cross-coupling reaction of aryl halides and thiols in aqueous media. Moreover, the heterogeneous catalyst can be easily recovered by filtration and reused for five cycles without significant loss in activity. (C) 2016 Elsevier Ltd. All rights reserved.
