Copper—Diamine-Catalyzed N-Arylation of Pyrroles, Pyrazoles, Indazoles,
Imidazoles, and Triazoles. — A two-step/one-pot combination of Cu-catalyzed halide exchange and the present coupling reaction can be applied for such cases, where
the aryl iodide reacts faster and/or more regioselectively than the corresponding bromide (second part of the publication cited in CI2004-50-034). — (ANTILLA, J. C.;
