摘要

The chemistry of the uranyl ion ([UO_2]~(2+)) has evolved remarkably over the past few years, with unexpected reactivity observed that challenge our understanding of this ion, and of actinides in general. This review highlights some recent advances in the field, focussing on the organometallic chemistry of the uranyl moiety, which is not well developed in comparison to lower oxidation states of uranium. The use of uranyl as a catalyst is highlighted and the newly developed supramolecular chemistry is described. The uranyl oxygen atoms have been considered as inert, but recent work has shown that is not necessarily the case and is discussed herein. Finally, reduction to the [UO_2]~+ ion will be discussed. The unusual reactivity of the uranyl ion, [UO_2]~(2+), reported during the past few years is highlighted. Organometallic and catalytic chemistry is reviewed and the use of uranyl in supramolecular assemblies emphasized. Oxygen functionalization and reduction to the pentavalent state is discussed.
