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.
1)碱金属还原溴[三(三异丙基硅基)]硅烷生成[三(三异丙基硅基)]硅基自由基,分离为黄色晶体。用X-射线单晶衍射法测定了硅基自由基的分子结构和晶体结构。结果表明,在制备规模的实验中可以进行稳定的硅基自由基的形成。硅基自由基磁性的研究代表了第一个环状硅基二阴离子underway.2)trans-1,2,2,3,4,4-Hexa-tert-buy1-1,3-cyclotetrasilanediyl)potassium,,它是由trans-1,2,2,3,4,4-hexa-tert-buy1-1,3-dibromocyclotetrasilane与苯中的钾反应合成的。化合物-苯络合物的X-射线晶体分析显示了一种新的超分子结构,其中化合物和苯交替堆积形成无限的一维结构。3)硅基中心的双自由基1,2,2,3,4,4-hexa-tert-buy1-1,3-cyclotetrasilanediyl),是由trans-1,2,2,3,4,4-hexa-tert-buy1-1,3-dibromocyclotetrasilane与苯中的钾还原而形成的红色晶体。晶体双自由基的X射线结构测定和磁性研究正在进行中。
