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.
芳烃是有机化合物的基本基团,在有机化学中起着重要的作用。相比之下,稳定的金属-芳族化合物如硅-芳族和锗-芳族体系的化学是新的,并且是最近开发的,其中骨架原子部分地被较重的第14族元素取代。本课题主要研究了由14族重元素组成的稳定芳香族化合物的化学、合成方法的发展、结构、性质和反应活性的分析,并通过环三硅烯的氧化脱硅反应成功地合成并表征了环三硅烯鎓离子。环三硅烯鎓离子具有近正三角形的三元环,表明其具有类似于环丙烯鎓离子的2π芳香体系的芳香性。另一方面,通过1,2,3,4-四溴环四硅烷的还原脱溴和额外的两电子还原合成了四硅环丁二烯二价阴离子的二钾盐,其作为具有6π芳香体系的环丁二烯二价阴离子的较重的类似物,具有由上下两个钾阳离子配位的大的弯曲的四元环,并且我们得出结论,较重的环丁二烯二价阴离子是非芳族的,这是因为平面三配位几何结构在带负电荷的有机硅化合物中不是优选的。此外,我们还成功地合成了6π电子芳香族化合物二硅锗环戊二烯离子。
