摘要：

Trifluoroacety]trialkyl(aryl)silanes, synthetic equivalents of trifluoroacetaldehyde, were prepared in good to moderate yields by reaction of 1,1-difluoro-2-trialkyl(aryl)silyl-2-trimethylsilyloxyethenes with Selectfluor(R). Sakurai reaction of fluorinated acylsilanes formed either the alpha-silylated ketones by means of Brook- and retro-Brook isomerization or, in the absence of Brook isomerization, homoallylic alcohols.
