Recent advances in transition-metal-free arylation by using diaryliodonium salts

Diaryliodonium salts are a class of reagents characterized by their stability, low toxicity, and high reactivity. These advantageous properties render them highly suitable for use as environmentally friendly and efficient electrophilic arylation reagents in a diverse range of chemical processes. In this overview, we concisely explore the arylation reactions of diaryliodonium salts that occur without the need for transition-metal catalysis over the past seven years. The objective is to enhance our comprehension of the recent applications of diaryliodonium salts. This, in turn, may uncover new opportunities for more in-depth investigations within this specific research domain, facilitating the development of novel synthetic methodologies and expanding the scope of their utility in organic synthesis.
