合成了一系列新颖的9，9-二烷氧基-9-硅芴类化合物，并对其结构和反应性能进行了研究。9，9-二氢-9-硅芴在氯化钯存在下与各种醇发生脱氢烷氧基化反应，得到相应的二烷氧基化产物，产率较高。通过X射线晶体学分析了一些新的9，9-二烷氧基-9-硅芴的结构。9，9-二烷氧基-9-硅芴对苯基溴化镁显示出非常高的反应性，以提供取代产物。
A series of novel 9,9‐dialkoxy‐9‐silafluorenes were synthesized, and their structures and reactivity were studied. Dehydrogenative alkoxylation of 9,9‐dihydro‐9‐silafluorene with various alcohols in the presence of PdCl2gave the corresponding dialkoxylated products in good yields. The structures of some of the novel 9,9‐dialkoxy‐9‐silafluorenes were analyzed by X‐ray crystallography. The 9,9‐dialkoxy‐9‐silafluorenes show remarkably high reactivity toward phenylmagnesium bromide to afford substitution products.
