of trifluoroacetaldehyde, were prepared in good to moderate yields by reaction of 1,1-difluoro-2-trialkyl(aryl)silyl-2-trimethylsilyloxyethenes with Selectfluor®. Sakurai reaction of fluorinated acylsilanes formed either the α-silylated ketones by means of Brook- and retro-Brook isomerization or, in the absence of Brook isomerization, homoallylic alcohols.
Trifluoroacetyltrialkyl(芳基)硅烷,三氟乙醛的合成等价,在良好的制备由1,1-二氟-2-三烷基(芳基)反应,以中等产率的甲硅烷基-2- trimethylsilyloxyethenes用的Selectfluor ®。氟化酰基硅烷的Sakurai反应通过Brook-和Retro-Brook异构化形成α-甲硅烷基化的酮,或者在不存在Brook异构化的情况下,形成均烯丙基醇。
