项目摘要

The following results have been obtained on the stabilization, syntheses, and structures and silyl radicals and the related open-shell species.1)The reduction of bromo[tris(triisopropylsilyl)]silane with alkali metals led to the formation of [tris(triisopropylsilyl)]silyl radical, which was isolated as yellow crystals. The molecular and crystal structure of the silyl radical were determined by X-ray crystallography. It was found that the formation of the stable silyl radical can be carried out in the preparative-scale experiment. The study on the magnetic properties of the silyl radical is underway.2)trans-1,2,2,3,4,4-Hexa-tert-buy1-1,3-cyclotetrasilanediyl)potassium, which represents the first example of cyclic silyl dianion, was synthesized by the reaction of trans-1,2,2,3,4,4-hexa-tert-buy1-1,3-dibromocyclotetrasilane with potassium in benzene. The X-ray crystallographic analysis of the compound-benzene complex showed a novel supramolecular structure, in which the compound and benzene are stacked alternatively to form an infinite 1-D structure.3)The silyl-centered biradical, 1,2,2,3,4,4-hexa-tert-buy1-1,3-cyclotetrasilanediyl), was formed as red crystals by the reduction of trans-1,2,2,3,4,4-hexa-tert-buy1-1,3-dibromocyclotetrasilane with potassium in benzene. Studies on the X-ray structure determination and magnetic properties of the crystalline biradical were underway.
在稳定化、合成、结构、硅自由基及相关开壳层物种等方面取得了如下结果:1)溴代[三(三异丙基硅基)]硅烷经碱金属还原生成[三(三异丙基硅基)]硅自由基,分离得到黄色晶体。通过X射线晶体学测定了硅自由基的分子和晶体结构。结果表明,稳定的硅自由基的形成可以在小规模实验中进行。2)以反式-1,2,2,3,4,4-六叔丁基-1,3-二溴环四硅烷为原料,在苯中与钾反应,合成了第一例环硅负离子反式-1,2,2,3,4,4-六叔丁基-1,3-环四硅烷二基)钾。3)通过反式-1,2,2,3,4,4-六叔丁基-1,3-环四硅烷二基的还原反应,得到了以硅烷基为中心的双自由基1,2,2,3,4,4-六叔丁基-1,3-环四硅烷二基(1,2,2,3,4,4-hexa-tert-bu 1 - 1,3-cyclotetrasilanidyl)的红色晶体。3-二溴环四硅烷与钾的苯溶液。晶体双自由基的X射线结构测定和磁性研究正在进行中。
