The chemistry of the f-elements has been marked in recent years by the impressive use of actinides in catalysis. These advances have allowed the actinide community to tailor organoactinide complexes for specific reactivities accomplishing a high level of sophistication. It is important to note that when comparing the actinides to transition or lanthanide block complexes, the actinides will sometimes exhibit complementary reactivities; however, most often, distinctive chemistries are displayed for similar organic transformations. Based on their unique electronic and steric characteristics, it is now possible to design new catalytic transformations. This article highlights the catalytic processes including the activation of small molecules, hydroelementations, coupling reactions, and polymerization/oligomerization of cyclic esters and epoxides.
