  摘要：

  将 Me(3)SiI 添加到 UO(2)((Ar)acnac)(2) (ArNC(Ph)CHC(Ph)O, Ar = 3,5-(t)Bu(2)C(6)H (3)) (1) 导致以中等产率形成 U(OSiMe(3))(2)I(2)((Ar)acnac) (2)。反应中还形成了 I(2) 和 ArNC(Ph)=CHC(Ph)OSiMe(3)，这是 [(Ar)acnac](-) 被 Me(3)Si(+) 提取的产物。相比之下，1 与 Me(3)SiX (X = Cl, OTf) 的反应仅导致形成 UO(2)(OTf)(2)((Ar)acnacH)(2)(Et(2)O ) (3) 和 UO(2)Cl(2)((Ar)acnacH)(2) (4) 分别。

  Reduction of Pentavalent Uranyl to U(IV) Facilitated by Oxo Functionalization

  摘要：

  Addition of 2 equiv of B(C(6)F(5))(3) to [Cp*(2)Co][U(V)O(2)((Ar)acnac)(2)] (1) [(Ar)acnac = ArNC(Ph)CHC(Ph)O; Ar = 3,5-(t)Bu(2)C(6)H(3)] results in the formation of [Cp*(2)Co][U(V){OB(C(6)F(5))(3)}(2)((Ar)acnac)(2)] (2) in good yield. Reduction of 2 with 1 equiv of Cp*(2)Co generates [Cp*(2)Co](2)[U(IV){OB(C(6)F(5))(3)}(2)((Ar)acnac)(2)] (3), also in good yield. This reaction is chemically reversible, as shown by the reaction of 3 with AgOTf, which regenerates 2. Interestingly, addition of only 1 equiv of B(C(6)F(5))(3) to 1 does not produce the monofunctionalized U(V) complex. Instead, the products of disproportionation, namely, 3 and U(VI)O(2)((Ar)acnac)(2), are observed in a 1:1 ratio.

  The reaction of 2 equiv of Ph3SiOTf with UO2(dbm)2(THF) (dbm = OC(Ph)CHC(Ph)O) and UO2(Aracnac)2 (Aracnac = ArNC(Ph)CHC(Ph)O; Ar = 3,5-tBu2C6H3) results in the formation of U(OSiPh3)2(dbm)2(OTf) (1) and [U(OSiPh3)2(Aracnac)2][OTf] (2), respectively, in good yield.

  2当量的Ph 3 SiOTf与UO 2（dbm）2（THF）（dbm = O C（Ph）CHC（Ph）O）和UO 2（Ar acnac）2（Ar aacac = Ar N C（Ph ）CHC（Ph）O ; Ar = 3,5- t Bu 2 C 6 H 3）形成U（OSiPh 3）2（dbm）2（OTf）（1）和[U（OSiPh 3）2（Ar acnac）2 ] [OTf]（2），分别具有良好的产量。

  The addition of 1 equiv of HSiPh(3) to UO(2)-((Ar)acnac)(2) ((Ar)acnac = ArNC(Ph)CHC(Ph)O; Ar = 3, 5-(t)Bu(2)C(6)H(3)), in the presence of 1 equiv of B(C(6)F(5))(3), results in the formation of U(OSiPh(3))(OBC(6)F(5)}(3))((Ar)acnac)(2) (1), via silylation of an oxo ligand and reduction of the uranium center. The addition of 1 equiv of Cp(2)Co to 1 results in a reduction to uranium(IV) and the formation of [Cp(2)Co]-[U(OSiPh(3))(OBC(6)F(s)}(3))((Ar)acnac)(2)] (2) in 78% yield. Complexes 1 and 2 have been characterized by X-ray crystallography, while the solution-phase redox properties of 1 have been measured with cyclic voltammetry.
