Reduction of the uranium(IV) thiolates Cp*2U(SR)2 (Cp* = η-C5Me5, R = Ph, Me, iPr or tBu) with sodium amalgam afforded the corresponding U(III) complexes Na[Cp*2U(SR)2] (R = Ph, 2a; Me, 2b; iPr, 2c) or the U(IV) sulfide Na[Cp*2U(StBu)(S)]. C-S bond cleavage of a thiolate ligand was also observed during the thermal decomposition of 2c into the sulfide Na[Cp*2U(SiPr)(S)], whereas 2b was transformed in refluxing THF into the thiametallacyclopropane complex Na[Cp*2U(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*2U(Si Pr)2], [Na(18-crown-6)][Cp*2U(StBu)(S)], and [Na(18-crown-6)(THF)2][Cp*2U(SMe) (SCH2)] been determined.
