项目摘要

Aromatic hydorocarbons such as benzene and naphthalene, are fundamental group of organic compounds, and also plays important roles in organic chemistry. In contrast, the chemistry of stable metallaaromatic compounds such as sila- and germa- aromatic systems, in which skeletal atom(s) are partially replaced by heavier Group 14 elements, is new, and have been recently developed. In this project, we investigated the chemistry of stable aromatic compounds consisting of heavier group 14 elements ; the development of synthetic methods, analysis of structure, property, and reactivity of them.We succeeded in synthesize and characterize cyclotrisilenylium ion by the oxidative desilylation reaction of cyclotrisilene bearing extremely bulky triorganosilyl groups. Cyclotrisileniylium ion has near regular triangle three membered ring indicating its aromatic character in analogy with cyclopropenylium ion with 2π aromatic system. On the other hand, dipotassium salt of tetrasilacyclobutadiene dianion as heavier analogue of cyclobutadiene dianion with 6π aromatic system synthesized by the reductive debromination and additional two-electron reduction of 1,2,3,4-tetrabromocyclotetrasilane, has large bent four membered ring coordinated by two potassium cations up and below, and we concluded that heavier cyclobutadiene dianion is non-aromatic by the reason why planer three-coordinate geometry is not preferred in negatively charged organosilicon compounds. Additionally, we also succeeded in the synthesis of disilagermacyclopentadienide ion as 6π electron aromatic compound.
芳族羟苯和萘之类的芳族羟基是有机化合物的基本组,并且在有机化学中也起着重要作用。相比之下,稳定的金属芳族化合物的化学(如硅烷和细菌系统)在其中骨骼原子(S)部分被较重的组14元素代替,并且最近已开发。在这个项目中,我们研究了由较重组14个元素组成的稳定芳香化合物的化学。通过蛋黄硅烷的氧化目的反应反应非常庞大的三甲硅烷基群群,我们成功地合成和表征了colotrisyenylium离子的合成方法,结构,性质分析和反应性的发展。环乙烯基离子的定期三角形接近三个成员环,表明其芳香特征与2π芳族系统类似于环丙基离子。另一方面,四边形环丁二烯dianion的二倍盐是通过减少脱环和额外的两种电源减少1,2,3,4-二甲基甲硅烷的大型bimomiomoipyclotetrasilane的含6π芳族系统的周环二烯dianion的较重的类似物,并具有二型均方体,并具有二型均方体的coordromipyclomiomipys and and Pots and Boint and ront and ront and in and Pot rone and in and Pot an得出结论,由于在带负电荷的有机硅化合物中,较重的环丁二烯dianion是非芳族的,因此刨床三坐标几何形状不是首选的。此外,我们还成功地合成了disilageryacyclopentadadadadadadide离子为6π电子芳香化合物。
