The multiply bonded derivatives of the heavier main group elements are among the most challenging targets for synthetic pursuits. Those of them featuring a double bond between the silicon and group 15 element are represented mostly by the silaimines -N═Si< and phosphasilenes -P═Si< with a very few examples of arsasilenes -As═Si<. In this contribution, we report on the synthesis and structural elucidation of the first stable stibasilene and novel phosphasilene and arsasilene derivatives, featuring an identical substitution pattern. A systematic comparison within the series phosphasilene-arsasilene-stibasilene is made on the basis of their experimental and computational studies.
重主族元素的多重键衍生物是合成追求中最具挑战性的目标之一。其中那些具有硅和第 15 族元素之间双键的化合物主要由硅亚胺 -N═Si< 和磷硅烯 -P═Si< 代表，只有极少数的砷硅烯 -As═Si< 的例子。在本贡献中，我们报告了首例稳定的锑硅烯以及新型的磷硅烯和砷硅烯衍生物的合成和结构阐明，它们具有相同的取代模式。基于实验和计算研究，对磷硅烯-砷硅烯-锑硅烯系列进行了系统比较。
