quinones, (b) copper complexes and (c) carbon nanotube-supported copper ferrite as catalysts in the presence of AgSeR-salts were also used for the synthesis of selenium-containing quinoidal derivatives. These new methods provide efficient and practical strategies for the preparation of selenium-based quinones. In addition, we have discovered nine compounds with potent trypanocidal activity.
