We recently reported the formation of a bridging carbonate complex [{(((Ad)ArO)(3)N)U}(2)(μ-η(1):κ(2)-CO(3))] via reductive cleavage of CO(2), yielding a μ-oxo bridged complex, followed by the insertion of another molecule of CO(2). In a similar strategy, we were able to isolate and characterize a series of mixed carbonate complexes U-CO(2)E-U, U-CS(2)E-U, and even U-OC(S)Se-U, by reacting bridged chalcogenide complexes [{(((Ad)ArO)(3)N)U}(2)(μ-E)] (E = S, Se) with CO(2), CS(2), and COS. These chalcogenido mixed-carbonate complexes represent the first of their kind.
我们最近报道了通过还原裂解 CO(2)形成桥连碳酸盐配合物 [{(((Ad)ArO)(3)N)U}(2)(μ-η(1):κ(2)-CO(3))]，生成 μ-氧桥接配合物，然后插入另一个 CO(2)分子。采用类似的策略，我们能够通过反应桥连的硫属化物配合物 [{(((Ad)ArO)(3)N)U}(2)(μ-E)]（E = S，Se）与 CO(2)、CS(2)和 COS 来分离和表征一系列混合碳酸盐配合物 U-CO(2)E-U、U-CS(2)E-U，甚至 U-OC(S)Se-U。这些硫属混合碳酸盐配合物是同类中的首例。
