The field of nonsymmetrical salen compounds has matured significantly during the last decade. These unsymmetrical salen ligands and their complexes have found widespread applications in the field of catalysis.
Therefore, the development of reliable and efficient synthetic methods for this kind of ligands and complexes have become increasingly important.
Arjan Keij gathers, in this microreview, the general methods available for the synthesis of unsymmetrical salen ligands and their complexes and highlights their applications in different areas of catalysis.This review is one of the most frequently cited articles published in European Journal of Inorganic Chemistry.
