卡宾稳定的二硅(1)与锂基二硫杂环戊烯自由基(2.)得到第一双阴离子硅三(二硫杂环戊烯)络合物(3)。值得注意的是,3的形成代表了碳烯稳定的二硅(1)作为硅转移剂的前所未有的利用。3的性质通过多核NMR光谱、单晶X射线衍射和DFT计算来探索。
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 of3represents the unprecedented utilization of carbene‐stabilized disilicon (1) as a silicon‐transfer agent. The nature of3was probed by multinuclear NMR spectroscopy, single‐crystal X‐ray diffraction, and DFT computations.
