The structure of 2-t-butoxy-2,4,6-trimethyl-4,6-diphenyl-(2α,4α,6α)-cyclotrisiloxane has been determined by an X-ray crystallographic study. The structure revealed confirms the validity of the basis of our 29Si and 1H NMR assignments previously made to configurational isomers of several model compounds, which are suitable for studying the stereochemistry of substitutions at silicon atoms in siloxanes
通过X射线晶体学研究确定了2-叔丁氧基-2,4,6-三甲基-4,6-二苯基-(2α,4α,6α)-环三硅氧烷的结构。揭示的结构证实了我们先前对几种模型化合物的构型异构体进行的29 Si和1 H NMR指配的基础的有效性,这适用于研究硅氧烷中硅原子取代的立体化学
