Highly efficient and reusable polystyrene-supported copper(II) catalytic system for S-arylation of potassium thiocyanate by aryl halides in water

An inexpensive, efficient and environmentally friendly copper(II) catalyst supported on polystyrene was successfully synthesized and used as a heterogeneous catalyst for S-arylation of potassium thiocyanate by aryl halides. Also this catalyst could be recovered and reused several times without any noticeable decrease in its catalytic activity. Copyright (C) 2016 John Wiley & Sons, Ltd.
