C–S cross-coupling of thiols with aryl iodides under ligand-free conditions using nano copper oxide as a recyclable catalyst in ionic liquid

Author affiliations

Abstract

A recyclable copper nanopowder catalyst in ionic liquid is effective for promotion of the cross-coupling reaction of various thiols with aryl iodides under ligand-free conditions. Compared to the usual organic solvents, [bmmim]BF4 exhibited higher performance with the advantage of being able to be reused for up to four successive runs.
