Abstract

Developing versatile methodologies to construct various nitrogen­-containing heterocycles is a crucially significant part of contemporary organic chemistry. This review summarizes recent developments on the formation of nitrogen-containing heterocycles triggered by diaryliodonium salts. Diaryliodonium salts, as electrophilic arylating agents in the presence of catalytic copper salts, can react with nitriles to give N-arylnitrilium cations, which are highly reactive species. These species can efficiently react with nucleophiles, including C-, N- and O-nucleophiles, to give the corresponding products. This strategy is not only efficient and convenient, but also enables the synthesis of diverse nitrogen-containing heterocycles such as quinolines, quinazolines, and phenanthridines.
