Copper(I)-catalyzed S-arylation of thiols with activated aryl chlorides on water

Copper chloride-catalyzed S-arylation of arenethiols is effected with activated aryl chlorides in neat water by using ethylenediamine as the pair ligand/base. This convenient, environmentally more friendly procedure for the coupling of aryl chlorides allows the arylation between sterically demanding coupling partners.
