甲硅烷基二价阴离子(1)与硫属元素(E)反应,不生成相应的甲硅烷基硫属化物,但可生成一系列杂环二甲硅烷基硫属化物(E = S(2),Se(3),Te(4))。在高温下,化合物4可以转化为化合物5,化合物2和3的Te类似物。通过(1)H、(13)C和(29)Si NMR谱和高分辨质谱(HRMS)对化合物进行了表征。此外,对化合物2-5进行了X-射线结构分析。还进行了DFT计算。
The reaction of a dipotassium silyl dianion (1) with chalcogenide elements (E) does not afford the corresponding silylchalcogenolates, but allows the generation of a series of heterocyclic disilylchalcogenides (E = S (2), Se (3), Te (4)). Under high temperature, compound 4 can be converted into compound 5, a Te analog of compounds 2 and 3. The compounds were characterized by (1)H, (13)C and (29)Si NMR spectroscopy and high resolution mass spectrometry (HRMS). In addition, X-ray structure analyses were carried out on compounds 2-5. A DFT calculation was also performed.
