Uranium‐sulfilimine chemistry. The preparation of Cp2*UCl2(HNSPh2) and its hydrolysis with HNSPh2 · H2O

The reaction of Cp2*UCl2 with HNSPh2 produces Cp2*UCl2(HNSPh2), which is the first structurally characterized complex of a sulfilimine. The hydrolysis of Cp2*UCl2(HNSPh2) with HNSPh2 · H2O yields a tetrauranium cluster whose heavy atom structure has been determined by x‐ray diffraction and which is formulated as a UIV/UV complex: [Cp*(Cl)(HNSPh2)U(μ3‐O)(μ2‐O)2U(Cl)(HNSPh2)2]2.
