Treatment of 6-iodo-4-oxa-3-sila-1-hexene derivatives with arylmagnesium bromide in the presence of a catalytic amount of a cobalt-diamine complex in THF afforded the corresponding benzyl-substituted oxasilacyclopentanes in good yield. The products were converted to 4-aryl-1,3-diols after Tamao-Fleming oxidation.
6-iodo-4-oxa-3-sila-1-己烯衍生物与芳基溴化镁在催化量的钴-二胺配合物的THF中处理,以良好的收率得到相应的苄基取代的氧硅杂环戊烷。Tamao-Fleming氧化后,产物转化为4-芳基-1,3-二醇。
