Reaction of carbene-stabilized disilicon (1) with the lithium-based dithiolene radical (2 ) affords the first dianionic silicon tris(dithiolene) complex (3). Notably, the formation of 3 represents the unprecedented utilization of carbene-stabilized disilicon (1) as a silicon-transfer agent. The nature of 3 was probed by multinuclear NMR spectroscopy, single-crystal X-ray diffraction, and DFT computations.
卡宾稳定的二硅烷(1)与基于锂的二硫烯自由基(2)反应,得到首个双阴离子三(二硫烯)硅配合物(3)。值得注意的是,3的形成代表了卡宾稳定的二硅烷(1)作为硅转移剂的前所未有的应用。通过多核核磁共振光谱、单晶X射线衍射和密度泛函理论计算对3的性质进行了探究。
