  Bispentamethylcyclopentadienyl uranium(IV) thiolate compounds. Synthesis and reactions with CO2 and CS2

  摘要：

  The bisthiolate uranium complexes [U(Cp*)(2)(SR)(2)] (R = Me,Pr-i, Bu-t, Ph) were synthesized by treatment of [U(Cp*)(2)(Cl)(2)] with NaSR; the crystal structure of [U(Cp*)(2)(SMe)(2)] was determined. Their reactions with CO2 or CS2 gave the insertion derivatives [U(Cp*)(2)(SR)(E2CSR)] (E = O and R = Bu-t; E = S and R = Me, Pr-i or Bu-t) and [U(Cp*)(2)(E2CSR)(2)] (E = O and R = Bu-t; E = S and R = Me or Bu-t); [U(Cp*)(2)((SBu)-Bu-t)((S2CSBu)-Bu-t)] was characterized by its crystal structure. Treatment of this latter with CO2 gave the mixed insertion complex [U(Cp*)(2)((O2CSBu)-Bu-t)((S2CSBu)-Bu-t)]. Thermolysis of the insertion compounds led to the reverse elimination reaction of CO2 and CS2. Reduction of [U(Cp*)(2)((O2CSBu)-Bu-t)(2)] with Na(Hg) afforded the corresponding U(III) anionic complex. (C) 1999 Elsevier Science S.A. All rights reserved.

  C−H and C−S Bond Cleavage in Uranium(III) Thiolato Complexes

  摘要：

  Reduction of the uranium(IV) thiolates Cp*U-2(SR)(2) (Cp* = eta -C5Me5, R = Ph, Me, Pr-i or Bu-t) with sodium amalgam afforded the corresponding U(III) complexes Na[Cp*U-2(SR)(2)] (R = Ph, 2a; Me, 2b; Pr-i, 2c) or the U(IV) sulfide Na[Cp*U-2((SBu)-Bu-t)(S)]. C-S bond cleavage of a thiolate ligand was also observed during the thermal decomposition of 2c into the sulfide Na[Cp*U-2((SPr)-Pr-i)(S)], whereas 2b was transformed in refluxing THF into the thiametallacyclopropane complex Na[Cp*U-2(SMe)(SCH2)], resulting from C-H bond activation of a SMe group. The X-ray crystal structures of [Na(18-crown-6)(THF)(2)][Cp*U-2((SPr)-Pr-i)(2)], [Na(18-crown-6)] [Cp*U-2((SBu)-Bu-t)(S)], and [Na(18-crown-6)(THF)(2)][Cp*U-2(SMe)(SCH2)] have been determined.
