  摘要：

  (C5Me5)2UMe2（1）分别与1当量和2当量的PhEEPh（E = S, Se）反应，生成(C5Me5)2UMe(EPh)（E = S，2；Se，3）和(C5Me5)2U(EPh)2（E = S，4；Se，5），同时伴随生成MeEPh。复合物2、3和5在室温下形成，但合成4需要加热至65摄氏度。将2当量的PhTeTePh与1当量的(C5Me5)2UMe2反应，生成4和5的碲类似物，即(C5Me5)2U(TePh)2（6），但当1与1当量的PhTeTePh反应时，发生C-H键活化，生成(C5Me5)2U(η2-TeC6H4)（7），同时生成MeTePh和CH4。

  Methods to separate the components of the equilibrium mixture of [(C5Me5)(2)UH](2) and [(C5Me5)(2)UH2](2) have been developed that allow their reductive chemistry to be studied. These actinide hydrides can act as four-, six-, and eight-electron reductants depending on the substrate with H-2 as the byproduct of a H- -> e(-) + (1)/(2) H-2 redox couple. This hydride reduction chemistry allows complexes of redox-inactive Th4+ such as [(C5Me5)(2)ThH2](2) to be four- and six-electron reductants. [(C5Me5)(2)UH](2) and [(C5Me5)(2)UH2](2) cleanly reduce 2 equiv of PhEEPh (E = S, Se) to form 2 equiv of (C5Me5)(2)U(SPh)(2) and (C5Me5)(2)U(SePh)(2) in an overall four-electron reduction in each case. [(C5Me5)(2)UH](2) and [(C5Me5)(2)UH2](2) also effect a six-electron reduction of 3 equiv of 1,3,5,7-cyclooctatetraene to [(C5Me5)(C8H8)U](2)(C8H8) and an eight-electron reduction of 2 equiv of PhNNPh to form 2 equiv of the U6+ imido complex (C5Me5)(2)U(NPh)(2). In each reaction, H-2 is a byproduct. This hydride-based reduction is also successful with the tetravalent thorium hydride [(C5Me5)(2)ThH2](2), which reduces 2 equiv of PhSSPh to (C5Me5)(2)Th(SPh)(2) and 3 equiv of C8H8 to [(C5Me5)(C8H8)Th](2)(C8H8) with concomitant formation of H-2. X-ray crystallographic data are reported on [(C5Me5)(2)UH](2), [(C5Me5)(2)UH2](2), and (C5Me5)(2)U(SePh)(2) as well as the thorium reduction products (C5Me5)(2)Th(SPh)(2) and [(C5Me5)(C8H8)Th](2)(C8H8).
