“…The C-H arylation of arenes, heteroarenes, alkenes, and alkanes by diaryliodonium salts has been achieved using a variety of different metal salts as catalysts; representative examples with some or all of these substrates are known with Pd [5], Pt, Au, Cu, Fe, Ir, Ni, and Ru salts [6]. Diaryliodonium salts are also known to arylate a wide variety of nucleophiles such as enolates, carboxylates, amides, alkoxides, halides, etc.…”
