ABSTRACT A transition-metal-free approach to facile synthesis of thiocyanato- and nitro-arenes was developed from KSCN (potassiumthiocyanate) or NaNO2 with diaryliodonium salts in good yields under mild conditions. The reaction was compatible with a variety of sensitive functional substituents such as halides and nitro and ester groups. The usefulness of arylation products has been realized. GRAPHICAL

Easily available aryl and heteroaryl thiocyanates were converted into the corresponding perfluoroalkyl thioethers via decarboxylation of potassium perfluoroalkylcarboxylates, catalysed by the inexpensive and environmentally benign iron(III) chloride.
