Transition-metal-free synthesis of thiocyanato- or nitro-arenes through diaryliodonium salts

<p>A transition-metal-free approach to facile synthesis of thiocyanato- and nitro-arenes was developed from KSCN (potassiumthiocyanate) or NaNO<sub>2</sub> 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.</p>
