通过相应的二溴化物与KC8反应制备了一种新的稳定的亚硅基，外消旋-N,N'-二叔丁基乙烯-4,5-二甲基-1,3-二氮杂-2-硅杂环戊烷-2-叶立德。与缺少两个甲基的类似亚硅基（在浓溶液或固体中四聚）不同，新的亚硅基没有表现出低聚倾向；相反，它以稳定的无色液体形式存在。
A new stable silylene, rac-N,N‘-di-tert-butylethylene-4,5-dimethyl-1,3-diaza-2-silacyclopentan-2-ylide, has been made by reaction of the corresponding dibromide with KC8. Unlike the analogous silylene lacking the two methyl groups, which tetramerizes in concentrated solution or as a solid, the new silylene shows no tendency to oligomerize; instead, it persists as a stable colorless liquid.
