摘要
探讨了二元离子 [Li2(Et2O)1.5][(SPh2P)2C] 1 与 Se 和 Te 的反应，结果表明反应取决于化学计量学。已分离出[Li2(THF)3(SPh2P)2CSe2] 2、[Li2(THF)4(SPh2P)2CSe4C(PPh2S)2] 3、[Li2(THF)3(SPh2P)2CTe2] 4 和[Li2(THF)3Et2O][(SPh2P)2CTe3C(PPh2S)2] 5 物种，并对其进行了结构表征。事实证明，这些产物对光和空气非常敏感，同时，这些产物的表征也证明了二元离子拦截 E2-4 短链的能力。
Reactions of the Geminal Dicarbanion Li2[C(SPPh2)2] with Selenium and Tellurium
The reactions of the dianion [Li2(Et2O)1.5][(SPh2P)2C] 1 with Se and Te were explored and shown to be dependent on the stoichiometry. The species, [Li2(THF)3(SPh2P)2CSe2] 2, [Li2(THF)4(SPh2P)2CSe4C(PPh2S)2] 3, [Li2(THF)3(SPh2P)2CTe2] 4 and [Li2(THF)3Et2O][(SPh2P)2CTe3C(PPh2S)2] 5 have been isolated and structurally characterized. While these products proved to be remarkably sensitive to light and air, the characterization of these products demonstrates that ability of the dianion to intercept short chalcogenide chains of E2‐4.
