  9,9-二烷氧基-9-硅芴的合成、结构和反应性

  摘要：

  AbstractA 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 PdCl2 gave 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.
