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.
