Uranyl derivatives are the most well-known actinide compounds, and they are characerized by their trans-dioxo arrangement.  These U-O mulitple bonds are extremely strong, making such molecules persistant and difficult to transform.  Our lab has demonstrated the use of redox-active ligands to activate strong uranium-element bonds in the past, and we have recently applied this methodology to break down uranyl containing species. We present the synthesis and characterization of new uranyl compounds featuring redox-active ligands, as well as analysis of their magnetic properties. Unusual paramagnetic, diradical uranyl species have been explored both for their electronic structure and uranyl functionalization chemistry. A rare example of scission of a U-O bond and conversion to an O-C bond is reported as well.
