LSitBu [L = PhC（NtBu）2]（1）与4，4 ′-二（二甲氨基）硫代二苯甲酮反应生成[1+2]环加成产物硅硫杂环丙烷3，该产物带有一个三元SiCS环。LSiC（SiMe 3）3（2）与3，5-二叔丁基邻苯醌反应生成[1+4]-环加成产物4。在3中，硅原子是五配位的，而在4中，它是四配位的。化合物3和4通过光谱和光谱技术表征。通过单晶X射线结构分析明确地建立了1、3和4的分子结构。
The reaction of LSitBu [L = PhC(NtBu)2] (1) with 4,4′-bis(dimethylamino)thiobenzophenone resulted in the [1+2]-cycloaddition product silathiacyclopropane 3, bearing a three-membered SiCS ring. The reaction of LSiC(SiMe3)3 (2) with 3,5-di-tert-butyl-o-benzoquinone leads to the [1+4]-cycloaddition product 4. In 3 the silicon atom is five- and in 4 it is four-coordinate. Compounds 3 and 4 were characterized by spectroscopic and spectrometric techniques. The molecular structures of 1, 3, and 4 were unequivocally established by single-crystal X-ray structure analysis.
