Applications of boroxide ligands in supporting small molecule activation by U(iii) and U(iv) complexes

Abstract: The boroxide ligand [OBAr2]− (Ar = Mes, Trip) is shown to be able to support both UIII and UIV centres for the first time.

“…With only one exception, the chelated structures close to the Berry pathway have either a tridentate calixarene ligand C (Scheme 2) that occupies the equatorial coordination sites of a TBPY [57] or a bidentate ligand that forms six-or sevenmember chelate rings spanning an equatorial and an axial position. [58,59] It must be noticed that most of the Berry structures concentrate in the proximity of the trigonal bipyramid, with only one structure beyond 50 % along the path to the square pyramid (Figure 9b). [58] The non-Berry structures, on the other hand, are widely spread throughout the shape map, suggesting that bi-and multidentate ligands with varying topologies have a strong influence in determining the molecular geometries.…”

“…To the best of our knowledge, reactions involving A and elemental sulfur and selenium to provide complexes 3 and 4 are the rst examples of any d-or f-block bimetallic m-oxo complex possessing the ability to activate elemental chalcogens, which in both cases typically requires access to low valent, highly reducing metal precursors such as U III , 7,[29][30][31][32]34 Yb II , 45,46 47 and 48) and Ni I . 49 This reactivity sheds light on how uranium reactivity differs from the d-block and remainder of the f-block elements, and how complexes containing groups considered inert by convention can be manipulated for productive transformations.…”
