afluorene anion 2 has been isolated and characterized by single-crystal X-ray analysis for the first time. Three tetrahydrofuran molecules coordinate with lithium atoms in the crystal structure of 2. 2 was reacted with a number of electrophilic reagents and it can be used as a useful reagent for generating various functional hydrogen-substituted silafluorenes. Treatment of 2 with 2 equiv. of chlor
首次分离并通过单晶X射线分析表征了1-hydro-1-lithio-silafluorene阴离子2并对其进行了表征。三个四氢呋喃分子在2的晶体结构中与锂原子配位。2与许多亲电试剂反应,并且可以用作产生各种官能氢取代的硅芴的有用试剂。治疗2与2当量。氯双(异丙基)膦的化合物得到氯取代的硅芴4。具有SiH–SiBr片段的8与IiPr 2 Me 2(IiPr 2:2,5-二异丙基-3,4-二甲基咪唑-1-基)导致形成Si-Si键裂解产物,NHC稳定的silacyclopentadienylidene 9。
