首次分离得到了1，1-二取代噻咯二阴离子2，并通过单晶X射线衍射对其结构进行了表征，2可作为双电子转移还原剂还原有机化合物和无机盐，并能以近定量的产率再生相应的中性噻咯，表明它是一种优良的还原剂。（Mes）2SiCl 2与2的还原反应选择性地以高产率得到环三硅烷（Mes 2Si）3，其尚未以纯形式用现有方法分离。
The 1,1-disubstituted silole dianion2has been isolated and characterized by single-crystal X-ray analysis for the first time.2can be used as a two-electron-transfer reducing reagent for the reduction of organic compounds and inorganic salts with regeneration of the corresponding neutral silole in nearly quantitative yields, indicating that it is an excellent reducing reagent. Reduction of (Mes)2SiCl2with2selectively yielded the cyclotrisilane (Mes2Si)3in high yield, which has not been isolated in pure form with the existing methods.
