Metallocalix[n]arenes in catalysis: A 13-year update

Aside from their applications in the fields of ion extraction, gas storage and molecular sensors, calixarenes have been extensively employed as ligands for metal complexation. Moreover, metallocalix[n]arenes have shown interesting catalytic activity in a plethora of reactions proving, in many cases, superior to other systems bearing different ligand scaffolds. In this review, we summarize the latest advances (post-2008) in the field, categorizing the complexes by metal center.
