Abstract
The
reaction of 2 equiv of Ph<sub>3</sub>SiOTf with UO<sub>2</sub>(dbm)<sub>2</sub>(THF) (dbm = <i>O</i>C(Ph)CHC(Ph)<i>O</i>) and UO<sub>2</sub>(<sup>Ar</sup>acnac)<sub>2</sub> (<sup>Ar</sup>acnac = Ar<i>N</i>C(Ph)CHC(Ph)<i>O</i>; Ar =
3,5-<sup>t</sup>Bu<sub>2</sub>C<sub>6</sub>H<sub>3</sub>) results
in the formation of U(OSiPh<sub>3</sub>)<sub>2</sub>(dbm)<sub>2</sub>(OTf) (<b>1</b>) and [U(OSiPh<sub>3</sub>)<sub>2</sub>(<sup>Ar</sup>acnac)<sub>2</sub>][OTf] (<b>2</b>), respectively,
in good yield
