Uranium−Sulfilimine Chemistry: Synthesis and Characterization of Cp*2UCl(NSPh2) and Cp*2U(NSPh2)2
摘要:
Two imido derivatives of U(IV), CP*2UCl(NSPh2) (1; Cp* = pentamethylcyclopentadienyl) and CP*U-2(NSPh2)(2) (2), have been prepared in high yield from CP*2UCl2 and LiNSPh2. Alternatively, 1 and 2 can be synthesized by treating CP*2UCl[(CH2)(2)PPh2] with anhydrous HNSPh2. CP*U-2(NSPh2)(2) is the first structurally characterized uranium bis(sulfilimide) complex. Its short U-N distance suggests significant uranium-imido multiple-bond character.
